This element are commonly known as 'bullies'. The turn on people on a whim. They often times just fight someone for the sake of fighting. They are often fueled by alcohol and drugs. They have a heighten sense of themselves. They should not be given any quarter. They have no right to live amongst us good people.
In previous decades this element was kept in check but nowadays they run amok with no fear of retribution. This situation has come about for several reasons not least of which is the general publics fear of being arrested, hauled before a court and possibly interned. If one fights back then the 'bully' and worse the police see you as the problem not the bully. This situation must stop.
People are being killed from protecting what is rightfully theirs. Not a day goes by without someone being maimed by some bully because they looked at the bully in a funny way.
This situation is simply intolerable. The police have a huge role to play in this and it is they who must not allow bullies to bring charges against those who are willing to fight for what is theirs or willing to fight for just walking down the streets.
This http://news.bbc.co.uk/1/hi/england/norfolk/6953609.stm is the sort of thing that happens when the police have lost all respect from the tiny 'bully' minority from amogst the very people they serve. People who take part in such things should not be allowed the same freedoms law abiding people have as a basic right.
The time is now for fighting back against the growing number of bullies on our streets. Forget the police and their inertia whenever you see or indeed if you are a target yourself, some bully attacking someone, anyone of any age, then step in and smack that bully into next week. Protect others as well as yourself and we shall all live in a better place.
