act of kindness..??no nothing close

Today I read about some teens who have done some kind of crime or misbehaved and filmed it and then later posted it or something related on a public website and later lead to them getting arrested or being put in court for the incident filmed. The person in article one was a man who had a car accident involving two other cars and was charged with drunken driving the lawyers later found a my space or face book that showed the man in the article had pictures of earlier the night and the pictures showed him with alcoholic beverages and these pictures were used to show his negligence in the accident.
The second article I read about talked about kids filming acts of misbehavior such as something called fencing this is when a bunch of kids are thrown through a line of fences lined in someones back yard. This was the creation of some one who just wanted to be look at by others in hopes that his views on this stupidity would get great numbers of views on a public site. after the stupidity of others these public sites have put up signs that say any act of violence or any such is not allowed also these sites have agreed to join with the police to catch any types of criminal acts done and posted up on these web pages.
I was asked why should we be careful of the things that we post on public sites my answer to that is every thing we post or write is traced to the IP address that we wrote from and is traceable,also another reason is that if we ever had some kind of accident we maybe judged by the things we post on public sites whether it be a positive or negative.
There was a case on the news and on many news papers later that week it took place in December it was about a couple of girls who beat up a man on the subway and this incident was filmed and posted on a public web page (you tube) and the girls involved were later put to curt and charged with assault on a older man. This is a great example because the girls in this incident didn't think that by filming this it would lead to them getting charges pressed on them by this man this victim of a harsh beating on a A train going home.
