Just last year, a documentary aired on the BBC called “The Jihadist Next Door,” which followed around a number of Muslim extremists in the UK who wanted to implement Sharia Law there, and had sympathies towards ISIS.

By the time the documentary aired, one of the jihadists followed (named Abu Rumaysah) had already left for Syria and appeared on ISIS propaganda as an executioner. Here’s a picture of Rumaysah in the documentary - and in ISIS propaganda not long-after.

It’s a shame the documentary didn’t inspire any vigilante justice - because it would’ve prevented one of Saturday’s terror attacks in London.

According to the Evening Standard, MI5 and police faced growing pressure today over whether the London Bridge murders could have been prevented after it emerged that at least one of the attackers was a known extremist who had been reported to the authorities.

Neighbours in the block of flats in Barking where “Abs” — one of the three alleged terrorists — lived said that he had been thrown out of his local mosque because of his views and had a reputation for aggressive behaviour.

Footage of the killer, who is understood to be aged 27 and of Pakistani heritage, has also emerged from a Channel 4 documentary last year in which he is seen among a group of radicals unveiling an Islamic State flag in a London park.

Other film of him berating police outside a mosque has also been published.

Well - congratulations to the BBC and the UK authorities for following around ticking time bombs and doing nothing about it

There are over 23,000 suspected jihadists being actively monitored by British intelligence- and by the looks of things, it appears that the punishments for public displays of “Islamophobia” carry a punishment more harsh than actually calling for Jihad.
