Hey Sukes, welcome to the Den of Evil.
First, empty headed comments on the internet are the rule, not the exception. Newspaper/news site threads, particularly local ones, are usually the worst. So I wouldn't despair too much.
Second, I generally see two major responses to crime problems or really any set of problems. 1) Address the root causes somehow or 2) combat, or worse just cover up, the symptoms. Addressing crime in Britain mostly follows path two, from what I've seen. Rather than addressing the causes of crime, the governmental response has been to ban guns, and now knives are getting the same treatment. Of course, the problem hasn't truly been addressed, so the problem continues, and the banning gets ever more ridiculous.
However, addressing root causes are usually much more challenging and complicated than the solutions usually put forth on this site. Ever increasing enforcement and ever increasing draconian punishments, a course pursued in the USA (so I'm not just picking on the UK

), is also just another method of combating the symptoms. I don't know what all the answers are, but they will involve more than tough sounding talk and putting more people in jail.
This response is also a typical human response, and you see it everywhere.
There is a thread active now about 3 states making filming the police in public illegal. Problem: abuses by the police, which are increasingly being documented. Solution: don't address the abuses, ban the recording. Very typical of this mindset. Addressing root causes is a long, difficult process, and it satisfies no one's emotional needs. So it usually isn't done. And the problems continue. Hooliganism in UK cities, police abuses in the US, drug crime in the US, etc etc etc.
