Footage circulating Friday shows three female officers surrounding a Christian street preacher in a busy shopping precinct.

One of them looks like she should still be sitting exams at school. The other two hover, phones out, expressions tight, as if they have been sent to defuse a bomb.

The clip is eight minutes of modern Britain in micro. A member of the public reports being "offended" by words. Officers arrive and the preacher is treated as the problem.

The all inclusive term 'hate speech' is waved around and 'intimidation' is offered as the hook for an investigation. The man citing Scripture is expected to justify himself to people who appear unfamiliar with the very statutes they are leaning on.

This is not law enforcement. It is customer service for the emotionally fragile.

As we hear in the footage, Sections 4A and 5 of the Public Order Act 1986 are the blunt instruments used again and again against street preachers.

Section 5 makes it an offence to use threatening or abusive words or behaviour within the hearing or sight of a person likely to be caused harassment, alarm or distress. "Insulting" was stripped out of Section 5 in 2013. There is a defence if the conduct was reasonable.

Section 4A is the heavier charge. It requires intent to cause harassment, alarm or distress, plus proof that harassment, alarm or distress was actually caused. Police guidance itself describes 4A as aimed at "more serious, planned and malicious incidents."

Yet here are yet more female police officers spewing those statutes at the guy as if they're citing parking restrictions.

Being offended by the Bible is not grounds for a public order offense. Reciting the Gospel in a public street is not automatically "threatening." Calling the encounter "intimidation" because a passer-by disliked the message does not conjure the mental element the statute demands. Courts have said as much, repeatedly, after officers have already cuffed, swabbed and bailed the preacher.

That distinction is lost on too many in uniform. In the new footage the officers look lost in it. One of them is literally a frightened child. The other two look scared of the conversation they started. The preacher is the only person on camera who appears to have read the law.

We've seen this all too often in Britain recently.

In another similar incident, a volunteer Met officer ordered 20-year-old gospel singer Harmonie London to stop performing "church songs" on Oxford Street, claiming she was "not allowed to sing church songs outside of church grounds."

The Met later apologised and admitted the officer "was mistaken," adding: "We're sorry for the offence caused and will take the learning forward."
