If you were arrested with no explanation, what would your friends and family assume you had done?

Ah, defensive beating, I see.
All in the name of protecting oneself, and their mates.

Or if I catch someone being a bully, or if I get caught up in something and it's the only way out. But I doubt it would actually ever happen, I'm actually pretty timid until I get ticked off.

Doesn't sound horrible to me. Such bullies and mean people are in exception to the rules of proper behavior.

I'd just be hoping the legal system didn't work the same way as the school system in that regard...

I'd hope for a fair understanding as well.
