Retaliation: Not suggested but I am reminded suddenly of a tale from school days. I heard it three times in slightly different guises — and much more vaguely another several times — from both points of view, but always about the same individual so I have no reason to believe it is not true. Also remember, this is the Nice Suburbs. This was crazy when I heard it in the 80s, and nigh-inconceivable now. I think this happened shortly post-war, say...1979, but could have been a bit earlier.
HS teacher lived on a corner. Before we all got crazy about privacy, they might even have actually published teacher info still. We didn't have addresses but DID have teacher phones, as well as ALL student's home phone numbers and addresses, in the directory when I was in grade school still. So, not a secret.
I am not sure what caused it, probably literally just that he lived on a corner, and the yard was flat enough, but once every few weeks, someone or other would take it upon themselves to cut the corner across his lawn. Often late at night, whooping and leaving beer cans. Once he planted some bushes and his wife some flowers, and those got run down, he started getting annoyed.
It's a weekend, he's in the garage, hears a shitbox car coming, and on his street there are no loud rattletraps routinely, so he /strongly suspects/ this is the rare opportunity for daylight culprits. He made off with some stuff from Vietnam. Some say a case, but regardless he had at least one spare smoke grenade. Not M18, M15. The bursting one.
Steps out of the garage, sees the stereotypical movie version of kids with beer bottles in a hopped up, primer gray coupe, hits his driveway at an angle, start into the yard, and he pulls and throws from right there. Grenade hits the ground and bursts just to the rear of the car, still on his yard.
Huge boom, trunk comes off, among other things. Leaves a big scar in the lawn. The car is still powered, drives off.
Done. No more driving through his yard. He went to the store and planted a new bush over the burned spot.
It at least one version, the car was being fixed in the auto shop at his school (primer gray, it was before this event I mean) and he brought the trunk lid with him on Monday to give to the auto shop teacher.
(If you want another delightful story of VN take homes and neighborhood trouble: shortest version of a VERY long and weird story I got first hand is guy was impoverished, ran a gypsy cab in the bad part of town, getting no end of trouble from literal local gangs as well as other cabbies, etc. One day puts together the looks-good but non-functional AK he traded for, brought back. Slings it, takes one loop around the block, looking calmly straight ahead, no eye contact. Goes home, back in the closet. Done. No more trouble, ever.)
