I have no tolerance for this crap, in fact, my tolerance is so low it's infinite numbers of sub-zero. And I don't think enough people show that type of disdain - enough for children to see it. Too often children don't get the justice they deserve and too often adults don't display a severe enough disdain that children can see that the adults are protecting them.
And to some extent, the law obstructs them from doing so. Yeah, these residents will likely face battery or assault charges. I'd take that chance.
It's about time that these evil incarnates get what they deserve.
