Turnip's suggestion for the apology isn't to apologise for reacting to the deed, but maybe your initial tone and just a way of reopening the door so a superior educational approach could be used to get the desired result. To stop the guy doing what he is doing.

Escalate it into a war and the next thing is some "neighbour" will have the Police on you for carrying your guns to the car. It all gets stupid too easily.

Turnip and I are just suggesting that there might be an alternative more positive way.
