Fighting is, of course, to be discouraged and it is right that it is punished in school. However the problem with fighting is that often schools were, and probably still are, inclined to treat both/all parties and equally guilty and deserving of the same sanction. However that is not always the case though schools are often not interested in finding out who "started it". It is also not always the case that one who throws the first blow is the one who started it and is to blame. Sometimes it can be the result of provocation or a normally pacific person can just snap. That isn't to say that there aren't times when all parties are culpable. It can be a tricky situation.
The description "normally pacific" does not seem to apply to Travis as this is not his first fight and I get the impression from the scenario that while this his second fight of the month it is not his second fight in the longer term. If Travis is blameworthy then suspension seems an inadequate response, in fact suspension either out of or in school seems pointless punishment, though it does temporarily take him out of circulation which is probably the point of the exercise.
While I do not believe in double jeopardy as a general rule this is an exception since I warned Travis about fighting after the last time and that I would "tan his bottom" if he did it again and that is what he can expect when we get home. I would actually argue that this isn't really double jeopardy anyway in this case because as Travis will not be facing corporal punishment or a detention when he is back at school, or even a full day of suspension, it would hardly even be single jeopardy otherwise.
When we get home I will ask Travis what happened. On the basis that both parties in a fight are not necessarily both equally guilty I will entertain the possibility that Travis was not at fault or there were extenuating circumstances and I am even willing to stretch "self defence" to include a reaction to provocation. However, given the previous fights he has gotten into I will be assuming that he is at fault and I that I will be thrashing him unless he gives me very good reasons not to. Travis will be made aware just how precarious his situation is because as soon we get in he will be taking off his trousers before he gets a chance to say anything. The position of his underpants depends on what he says next.
If Travis cannot convince me that he couldn't have avoided the fight his underpants are coming off and I am tanning his bare bottom with something suitable, probably an OTK slippering with a warning the belt may be used if there is a next time, but it will depend on the circumstances of the fight to some extent.
Hopefully this will make Travis think twice, or more than that, about getting into another fight. If not then I wonder if he might benefit from some boxing, at a properly run club, which does seem to help some young men but maybe Travis is too young for that at 11, or maybe it might may things worse.
Anyway, fighting is now a double jeopardy offence for Travis unless there are extenuating circumstance.
