A couple of years ago I watched an episode of TCR on YouTube from the 90s about certain pubs in the Gtr Manchester area (Salford I think) being turned over by violent protection racketeering gangs which were eventually forced to close, even with innocent punters attacked themselves. Dead cringeworthy and terrifying, and thank God I never had the misfortune to go anywhere near those hellholes!

It didn't say the original airdate or year of said episode on YouTube, but it was no doubt around the time of Manchester being nicknamed 'Gunchester' (and likewise, Nottingham subsequently being nicknamed 'Shottingham').
