To be fair this is no worse than what it was like 11 years ago when I first moved here from SE England but I’m originally from London so have seen a lot worse. If anything the cops are doing a decent job of catching the people who are committing the worst offences, but more needs to be done to work out why it is happening.
I wouldn’t say I’m more apprehensive of cycling around town which I do at all sorts of hours, but I generally avoid “talking to strangers” and ride at 20-30 km/h, which leaves a lot of potential trouble far behind in the distance. Traffic safety is far more of a concern to me than anything.
I don’t go into town for “fun/leisure” any more since about 7 years and whilst I never felt specifically threatened always thought everyone in the town was on a “short fuse” (irrespective of whether they have anything to do with drugs/alcohol) and trouble could erupt at any moment.
