I have spent a lot of time in the UK over the past 8 years or so. I'd encourage you to visit and observe with your own eyes and talk to the locals, rather than relying on media accounts.... The situation is nowhere as "bad" as what seems to be recounted by the talking heads.
Similarly, I was in Stockholm during the time of the horrible truck attack in downtown Stockholm. The location of the incident was ~1 block from my lodgings. At the time, American media was full of lurid descriptions of dangerous "no-go" zones in Stockholm. I went to those zones, observed the situation with my own eyes, talked to the residents - it was nothing like the media was reporting.
