Identifying a five year old burned corpse is no fun. Don't hand a woman her dead husband's melted dog tags. Kids carry around ammo cans all the time, even to school. Nothing kills the romantic mood like a coffin in your dining room. Nice people don't hide veteran's artificial legs.
Stilts are pretty handy for peeping toms.
Getting spray painted sucks. Every school has a hatchet or two hanging around. Never let an antisocial teenager sing the National Anthem. Unamplified country music can muffle a gunshot. Replica cannons are fully functional and deadly accurate.
