Unfortunately Silas, you and many others are victims of the current culture where many people feel that they need not be accountable for their actions.
Coupled with a very liberal attitude towards crime, people feel that it is ok to misbehave, as there is little chance that they will be prosecuted.
Most of us do not want to get involved, because we fear the unknown...we do not want to be attacked if we catch these vermin misbehaving.
A good example of this is what happened on the evening of June 15. Despite the overwhelming video evidence, we still are not able to bring these people to justice in a timely fashion. And I have no faith in a court system that seems to not be able to have punishments fit the crime.
We all as a society, are to blame. Because we chose to put up with it.
