Met chief defends knife attack officers after Greens criticism

On Wednesday, Essa Suleiman, 45, stabbed two Jewish men — Shloime Rand, 34, and Moshe Shine, 76 — in the north London neighbourhood of Golders Green in an attack the Metropolitan Police formally declared a terrorist incident. Officers Tasered Suleiman and repeatedly kicked him in the head while attempting to prise a knife from his hand; he remains in custody on suspicion of attempted murder. Metropolitan Police Commissioner Sir Mark Rowley subsequently wrote to Green Party leader Zack Polanski condemning him for sharing a post that criticised the officers' conduct.

When police shoot a knife-wielding suspect, is the question whether they had to, or whether society failed to help that person before they became a threat? London's police chief and Green Party critics are answering very differently.

Polanski's post accuracy versus accountability

Liberal

The principle that police power requires public scrutiny is sound — but principle does not launder a factually wrong claim into accountability. Polanski's repost described officers kicking a man 'already incapacitated,' a specific factual assertion that the Metropolitan Police Commissioner directly contested, and that Polanski's own party admitted he shared without knowing the full picture. That is not asking questions. That is giving a politician's megaphone to an unverified narrative hours after two Jewish men were stabbed in the street.

Conservative

You're drawing a distinction between 'raising questions' and 'amplifying a viral post' — but that distinction assumes the official version is reliable enough to anchor accountability to. The IOPC exists precisely because institutional self-investigation failed communities repeatedly. Polanski was wrong to state contested facts as settled, but the underlying instinct — that a clip showing apparent excessive force deserves scrutiny — is not reckless. It's the reason oversight bodies get triggered at all.

Liberal

The IOPC argument would hold if Polanski had demanded an IOPC investigation. He didn't — he shared a post with specific factual claims his own party immediately walked back. That's not triggering oversight, that's publishing misinformation and calling it principle.

Conservative

Fair — but 'he should have routed it through proper channels' is only persuasive if those channels were visibly in motion, and they weren't yet. The post was wrong in content; the impulse behind it is harder to dismiss than you're allowing.

Chilling effect on officer intervention

Liberal

Commissioner Rowley's warning about a 'chilling effect' is not institutional defensiveness — it identifies a real operational mechanism. When unarmed officers face split-second decisions about whether to physically subdue a suspect they believe may be wearing explosives, their calculus cannot include viral condemnation from a party leader who hasn't seen the operational briefing. The lesson officers learn from that pressure is to hesitate, and hesitation in Golders Green that day could have meant Shloime Rand and Moshe Shine did not survive.

Conservative

The causal chain from Polanski's repost to an officer hesitating in a future attack is speculative — officers respond to immediate lethal threats, not social media timelines. And there's a real cost to the other side of that argument: if elected officials stay silent every time a use-of-force clip goes viral because they fear the 'chilling effect' accusation, you've effectively granted police a post-incident exemption from democratic scrutiny whenever the underlying crime is serious enough.

Liberal

No one is proposing silence — the argument is that scrutiny should be accurate before it's public. Demanding the IOPC investigate, asking the Commissioner to explain the force used at a press conference: all of that applies pressure without broadcasting a contested factual claim to hundreds of thousands of followers.

Conservative

That's a reasonable distinction in theory. In practice, 'accurate before public' has historically meant 'never public' — and that's why the instinct to push immediately, even imperfectly, exists in the first place.

Duty to Jewish community reassurance

Liberal

Golders Green is one of Britain's most visibly Jewish neighbourhoods, the attack was declared terrorism, and Prime Minister Starmer was booed when he visited — a measure of how frightened that community already felt. In that specific context, the political obligation on every elected figure was unambiguous: these men were targeted because they are Jewish, this is intolerable, and the state will protect you. Polanski's repost didn't add to that reassurance. It handed those who want to undermine confidence in the police response a platform with a party leader's name on it.

Conservative

You're framing reassurance and accountability as if they're mutually exclusive, but Jewish communities have spent decades being told to trust the state and finding that trust unreciprocated. The Golders Green community's fear is real — and so is their right to know whether the force used in their name was proportionate. Prioritising visible solidarity over hard questions isn't automatically what that community needs.

Liberal

The community that booed Starmer was not demanding an investigation into officer kicking technique — they were demanding safety. Polanski's post spoke to neither of those things. It spoke to a different political audience entirely.

Conservative

That may well be true of this post, at this moment. But 'the community wasn't asking for this' is a dangerous standard — communities under threat often want validation and protection simultaneously, and elected officials serve both demands.

Proper channels versus real-time public pressure

Liberal

The IOPC was built precisely because institutional self-investigation failed — that history is why liberals should understand the difference between the mechanism and the reflex. Referring a contested use-of-force incident to independent oversight is accountability that produces findings. Sharing a viral clip with a specific contested factual claim is accountability that produces headlines. Those are not the same thing, and conflating them damages the credibility of the oversight infrastructure the left spent decades building.

Conservative

The IOPC is genuinely slow — investigations routinely take years and produce findings long after public memory has moved on. Telling communities that the appropriate response to watching what looks like excessive force is to file a referral and wait is asking them to trust a process that has historically let them down. Real-time public pressure is often the only thing that makes official channels move at the speed justice requires.

Liberal

Slow is a reason to reform the IOPC, not a license to publish unverified factual claims. And if the argument is that pressure accelerates official processes, Polanski could have applied that pressure by demanding an investigation — not by endorsing a specific narrative before the facts were established.

Conservative

Demanding an investigation without naming what concerned you about the footage is a statement that disappears. The clip is what moves the needle — and you know it. The question is whether the facts underneath it justified the amplification, not whether the mechanism of pressure was appropriate.

Green Party's own concession as verdict

Liberal

The most damaging line in this episode came from inside the Green Party: Polanski 'doesn't know the full picture.' That sentence was offered as damage control — but it is actually the reason not to have posted in the first place. If your own party acknowledges you acted without full information, and the Met Commissioner calls the commentary 'inaccurate and misinformed,' and Liberal Democrat MPs call it 'utterly disgraceful,' what happened is not imperfect accountability. What happened is that an elected official prioritised the moral satisfaction of appearing critical of authority over accuracy, at the worst possible moment.

Conservative

That concession is damaging, yes — but notice what it doesn't concede: that the underlying questions about the force used were illegitimate. 'He didn't have the full picture' is a criticism of timing and sourcing, not a verdict that there was nothing to scrutinise. Every politician who ever challenged a contested official account before the investigation concluded was technically acting without the full picture. The standard you're applying here would silence scrutiny almost by definition.

Liberal

There's a difference between acting without a complete picture and stating a specific factual claim — 'already incapacitated' — that your own party then walks back. That's not scrutiny without perfect information. That's publishing a claim you cannot verify and calling it principle.

Conservative

Agreed that the specific framing was indefensible. But stripping out that framing, the question underneath it — was the level of force proportionate? — remains open, and someone has to be willing to ask it aloud.

Conservative's hardest question

The argument that real-time criticism creates a 'chilling effect' on police intervention is difficult to prove with precision — officers respond to immediate threats, not social media timelines, and the causal chain from Polanski's repost to future officer hesitation is speculative. A critic could reasonably argue that robust post-incident scrutiny is exactly what maintains the public trust that allows police to act decisively in the first place.

Liberal's hardest question

The IOPC is genuinely slow and often produces findings too late to matter, which gives the progressive case for real-time scrutiny real force — if official channels reliably failed in the past, telling communities to trust them again is asking a lot. It is not easy to dismiss the concern that 'wait for the process' has historically been how accountability disappears.

The Divide

*Even as liberals unite against antisemitism, they're fracturing over whether Polanski's police criticism was legitimate accountability or reckless amplification.*

PROGRESSIVE LEFT

Valid questions about police use of force and treatment of potentially mentally ill suspects deserve scrutiny even after terrorist attacks.

“We do need to understand more about the response.” — Green Party spokesperson

CENTRIST LEFT

Polanski amplified unverified anti-police narratives in the aftermath of an antisemitic terror attack on a Jewish community, causing serious harm.

“Utterly disgraceful.” — Luke Taylor MP (Liberal Democrats)

The Verdict

Both sides agree

Both sides agree that the officers arrived unarmed within minutes to a suspect feared to be carrying explosives who continued resisting after being Tasered, and that this operational context matters significantly to assessing the force used.

The real conflict

FACTUAL: Whether the suspect was 'already incapacitated by Taser' when officers kicked him — Conservative and Liberal positions both cite Rowley's direct contradiction of this claim, but Conservatives treat this as settled truth while Liberals frame it as the kind of operational claim that demands independent investigation.

What nobody has answered

If the IOPC process is genuinely too slow to produce meaningful accountability (as Liberals concede), and real-time political pressure is the only mechanism that forces institutions to act, at what point does demanding that scrutiny wait for official channels become complicit in the very accountability failure Liberals are worried about — and who gets to decide when that threshold is crossed?
