must have been a slow tech news day for El Reg.
The met have been doing this for years, since UK Garage and other similar genres with aggressive lyrics and a culture of confrontation / actual fighting amongst rival crews led to an increasing problem with violence at these events.
if muppets didn’t go around shooting up clubs and each other because they got offended by some lyric or just wanted to start beef to look “hard” then the feds wouldn’t have to pull off these kinds of stunts.
I live in a town where we lost our biggest late night venue due to this gang culture and the cops now view all dance music events as a risk.
It may seem excessive but you do have to ask yourself why the cops didn’t do it 10 years ago – the technology was there, maybe it does come down to problems within the entertainments industry?
