Actually that's bollocks. Violence has not reached an 'unacceptable' level, and people aren't attacked at bus stops
in the manner you describe. We have had knife attacks, one was a Muslim who was killed by another for 'heresy' but most are gang members against gang members with young people mostly being the victims though not all victims were gang members. Knife crime however is going down, it remains the domain of the gangs who are always going to be a problem as the US knows and everyone stands at bus stops now waiting for buses nothing else. You have grasped the wrong end of the stick and it's the shitty end. Perhaps this can explain what you think you know. I notice that you don't quote your sources, please, you don't live or work here you actually have no idea what is happening here, I suspect you also believe our cities have no go areas for non Muslims too ( a hint, they really don't)
Whatever happened to London's knife-crime epidemic?
"While there are myriad statistics available to paint whatever picture you want, most criminologists agree that violent crime has been in persistent decline since the mid-1990s."
