School Safety and Appropriate Punishments

I would like to take this opportunity to thank all of you who have read about my experience. Your support has been encouraging. Like I've said, the whole situation is still fresh in my mind. I'm finding that blogging about it is very cathartic. I am able to get my feelings out and think through a lot of things. Thanks.
I've taken some time off since the position I was subbing for was filled by a full time teacher. I did work for a week after I was threatened, but the kid that threatened me was not on the campus. Had you asked me a few weeks ago how safe I felt at my school I would have told you I felt totally safe. After all, I graduated from that school. I felt just as comfortable as a staff member as I did as a student. Well, now it's a different story. I realize what a security nightmare my school must be. There are approximately 35-40 outside rooms each containing an entrance. There are about 11 formal entrances to the school. Our school has no metal detectors. The to schools credit they do lock all except two formal entrances once school begins. Teachers are not suppose to open their outside doors in their rooms. The school has cameras, a 4-5 person security team, and a police officer liaison. However, all of this aside, there is no way for them to protect me.
I've had to change my life. I am ashamed to admit that I never made myself aware of my surroundings. I was about the most oblivious person you could ever meet. Now, I find myself noticing every person that walks into the bowling alley that I work at. I scan rooms to see who is there (at work, at restaurants, everywhere). I look around when walking out to my car. I actually stop to ask that people see me out to my car, especially at night. So, I guess this whole ordeal has taught me to cognizant of my surroundings.
I now find myself thinking about what an adequate punishment should have been. The school implemented a 5 day OSS punishment on this boy because he had an almost nonexistent discipline record. The boy then competed in the schools version of a male beauty pageant. It is a very popular event. The boys that participate in it are held in high regard among their peers. I have a friend who is currently a student at the school. Her mother was one of my professors in undergrad, and we've remained close. This girl has informed me that pretty much the whole school knows what happened to me. There is nothing I can do about that. I figured it was inevitable that word would get around.
I don't know what is an acceptable punishment. I know I don't think 5 days of OSS is it. In addition, I certainly do not think that being allowed to participate in an event where the participants should represent the best of our school was appropriate. Where do you draw the line, though? My goal is not to ruin this kid's life; however, I want to be sure he understands the seriousness of his actions. I would feel better knowing that he is getting some sort of counseling. He clearly does not grasp why his actions were inappropriate nor why I reacted the way I did. I find that disturbing.
What do you think? What is an appropriate punishment? Should there be some sort of ban on social events for students who engage in heinous behavior? I've heard on the news that the Flint Schools are grappling with this issue. Stemming from an incident regarding football last fall, the Flint Schools are deciding what level of participation students convicted of a crime should be given. While my student was not convicted of a crime, I do think that some guidelines need to be put in place. What are your thoughts?
