It is a pain sometimes to report people. It takes time and can cause other problems. You need to decide if the incident is serious enough to take action. One incident took place during the time I was in college and working and it involved a police report, court and later the individual stalking my family while I was at work. The individual went head on at me and did a face plant on a tree. Then he tried to make me liable for his injuries. when he got no satisfaction from the court he than obtained my address and several times intimidated my wife.
