It has got worse over the years but compared to the rest if Europe its still very low.
It does need to be tackled obviously and its only some areas that are effected by it, luckily living in Wales we dont seem to have the same issues as England has, people are a lot happier here

also it might have something to do there is not as many immigrants here, there are rough areas but the kids around those areas only tend to steal cars and rob, they dont carry any weapons cause like that young guy said in the doc, they dont feel as if they need to carry weapons to defend them selfs.
