The kids were idiots, but he was a grown man running for office. Serious lack of judgement and self control there. If he was a 6'2" 250lb. employee seen on video body slamming a 14 year old kid, he would probably be job hunting if he were salary.
He doesn't know the age of those kids. They were the ones who were violent... a man can protect himself and his property. When does the violence from the left end, when we stand up for ourselves.
Pushing a young teen girl off the curb out into street traffic and body slamming a little kid are a little beyond the pale. The dumb ass kids rattled the adults into a really messy incident. Betcha he doesn't get elected.
Grown adults who were raised with manners, decorum, and respect for others are caught off-guard by the complete lack of that in many youngsters today; they are more akin to wild dogs, than decent young people.
That is a difficult adjustment for people who are actually civilized to make, especially in the moment. If you have never seen a rabid dog, you might mistake it for Fluffy until it's too late, and you've already been bitten.
