You were assaulted in front of witnesses and, if he touched you, you were also a victim of battery. This is a crime. At a minimum. it needs to be handled by Skepticon and you need to make a decision if criminal charges need to be filed. If this person comes out at 4 a.m. to threaten you, one can be fairly certain he has done it to other people and/or will do it in the future. Please don't be like the Catholic Church & sweep criminality under the rug because of appearances. This person needs to realize that what he has done is a crime and he needs to stop. If he needs drug or alcohol abuse or anger management treatment, this might be the warning he will heed.
