Either way, it’s assault. My God, that wasn’t even a “slap”...more a brushing against the kid’s head. If the parents couldn’t do the job of raising a respectful, patriotic young man, it’s nice to have a few old timers around to teach the youth some respect. I understand the kid’s right to not stand, but apparently the “slap” was effective. Good for the old guy...
How about keeping your hands to yourself and not trying to impose your will on someone else? Are you going to smack someone because they wore a different jersey too? Quit being a bully and start defending freedom.
