You should know that is was not stupid of the police to say they use mypsace to catch these guys. The people using the myspace are the stupid ones. I think its pretty logical for law enforcement to turn to the web. Nothing like committing a crime and providing the police evidence via the internet.
My point is , this is not uncommon. Law enforcement checks MANY websites in most investigations, esp. those that seem gang related. And this one- definitely MS13- the machetes are a mark of MS.
It’s stupid for the police to disclose their investigative techiniques. MySpace could have been a continuing gold mind to be harvested but not since the police disclosed its value in fighting crime.
