Regarding the poor immigrant families in my country, mostly of arab or maghreb origin, are often found in these kind of situations, firstly because they are immigrants and most of them have difficulties (the father left, etc), but also secondly due to their islamic culture, or sometimes of some african culture. Not that to say the culture is bad, at the contrary, but there is a cultural fact which consists to take for granted that a son is the rightful heir of the father, thus the next in line for the family, and can only be grounded/punished by the father himself. The father is often absent, or just does not have the time to care because he is struggling to give his family a decent living. The mother has absolutely no right to even criticize the son in a lot of cases (cultural problem), and just has to educate him in his daily life, at the contrary of daughters, who follow a very strict moral code. This is blatant in real life, especially with teens, where girls are terribly shy and submissive, and where guys are provocative, insulting, lacking of elementary respect, and basically think they can do what they want.
These are cases where foreigner cultures does not blend well with the western culture. I do not know how exactly it is in England, but I would not be surprised to see it is not that different.
Regarding religion, well, yes, this is another complex debate. I would say that religion gave us with time our own moral basis (we can't deny all that our ethics are at least a little based on christian, islamic or orthodox religions). By these ethics right or wrong. Though now, as much as I admit to follow unconsciously these basics, I have never believed in anything, much less in God(s), and am a fervent agnostic. As said above, this does not prevent me to follow my own strict moral code, because I had an education.
The thing is, we have courts for justice. We have police for protection. If cars are being taken and burned and businesses are being robbed and torched, I'd like to know that the police I'm funding with my taxes are going to do their job. Why should I have to suffer (property destroyed, etc) just so that the police can keep the kid gloves on while dealing with the mob?
Of course, if the police does not do its job properly... By the way, this is also one of the issues in Europe these days. Can't speak for all countries, but our youth is somewhat delusionned in a police they consider sometimes corrupt of abusive with its authority.
I understand what you're saying Lyn, but I would counter-argue that if things like this can happen and justice ISN'T done, then it's clear proof that our "justice system" needs review. You're not making an exception for them, you're learning from your mistakes and making improvements to the system based on experiences.
Justice is not doing its job ? I am asking genuinly here, I have no clue at all.
