And that doesn't have to be when just the food supply fails....people aren't trusting police will respond...here's an example of a parent taking action to to protect her son from hoodlums in the US.....
The mother is first seen screaming... 'Get the f*** away from my kid, you motherf*****'.....One of the teens can then be heard telling Tracy Leeser,.... 'You don't know s***' before saying, 'your son's gonna get your a** beat right now, I'll beat your son's a** right now'........ Leeser pulled out the gun from her shorts, yelling, .....'you wanna beat my a**?' as she points it at one of teens, who yells 'come on shoot me, shoot me'.......Even with a gun pointed in their face they remain brazen though the parents repeats many times..."Leave my son alone"........
I’d have shot him dead on the spot.
