My middle school was like this. They had a "zero tolerance" policy on fights, which meant if you were in one, you were supposed to get suspended.
In reality, it did not actually work this way. I did get into at least one fight where administration got involved, and they let me off the hook. (Neither of us got suspended, in fact.) In my own view, I 'started' that fight although I did not 'instigate' it, not that the difference matters much. Some kid in line for PE kept kicking the back of my shoes, and after the fourth or fifth time, I started punching him.
