People are too restrained. If we all lived in genuine communities where we all genuinely loved our cities, towns, villages, etc, we would never let shite like this happen in the first place.
We've all been guilty of turning our heads, walking by, and letting it happen. Doing so has resulted in the scum rising to the top... they are 21st century celebrities, and hundreds of thousands of idiots watch them on videos like we've seen posted on here. Stop feeding the beast.
We've lost decent societies all over the UK. The public should apply pressure on local councils, police etc to do their jobs, and get the shit off our streets.
Unfortunately, it won't happen, because we live in a lazy society where people prefer to just close their curtains to reality, and watch fakery on their TVs and phones. Society is guilty.
