Just one example of many and another off the top of my head

I do remember while there were some cases of teens killing people in the 2000’s, they were few and far between, now it’s like you got to watch out for teens rather than adults and there’s a very potent hazard of being killed by a pack.

What happened? it doesn’t seem to be affecting one area of the UK either but most places of the UK at once. what’s going on with British teens?
