The solution is to stay out of areas where these feral “youths” gather, but we can’t stay hiding in fear.
Arm yourself.
I always carry a 4” folding knife with me since Kalifornia frowns upon the concealed carry of firearms.
One good thing about knives is that they don’t run out of bullets.
If I find myself caught up in a pack of feral “youth” causing havoc, I will indiscriminately start slashing away at throat level.
Although a gunshot will usually clear the premises instantly, it’s just not practical for me to carry, although that day may be coming.
Just my way of doing business. Your mileage may vary.
I'm willing to take the hots and a cot if things go south. What I won't do is be a victim.
