I just read the incident report. Regardless of what was thrown at the house. The A's believed the protesters were throwing rocks.
They are well within their rights to go out into thier yard and confront anyone.
People react differently to different situations. GA is a man who, to me, seems fed up with everything that is going on. He is trying to protect his family, whether or not it is the "correct way" is beside the point.
It took two 911 calls, and two trips from the police to correct the situation. This is only going to escalate into something worse.
These protestors are making it about something other than Caylee. What they are about to do create another tragedy. Someone else is going to hurt if this witch hunt of the A family is allowed to continue.
They have every right to say what the want, and to protest all they want. They do have the right to provoke a violent situation. They are light the fuse on a bomb and when it goes off they wonder why they got burned.
