Dude, if a 20 year old attacks a 70 year old woman, the time for skinning those smoke wagons has passed, the thug that didn't need a gun now has one.
Now, on the other hand, here's a little vignette from my youth that may entertain you, it did me...
When I was 17, in the summer between my junior and senior year in high school, I was living on my own in an apartment in South Florida. Me and high school buddy had a few beers and went walking down the sidewalk on A1A. We saw this old, old guy jogging down the sidewalk doing a Rocky thing, kind of shadow boxing as he jogged. My friend thought this was funny. I had a lot more respect for my elders. So my idiot friend makes fun of the guy, loud enough to be obnoxious. The guy hears him and basically scolds him. My idiot friend gets more obnoxious. The old guy, I'm guessing 75 years old, basically dares my friend to say something to his face. My idiot friend, a pretty aggressive guy in his own right, laughing the whole time, ignoring my admonitions, does just that, walks right up to the guy and laughs in his face.
This 75 year old guy rabbit punched my idiot friend in the face about 30 times in as many seconds and he crumbled like a bag of meat.
The guy looked at me, like he was wondering if I wanted to bite off a piece of this action.
I just looked back at him, laughed, told him that was awesome and I hoped I would be half as bad ass when I was his age.
He waved and kept on jogging.
Respect your elders.
