If the rioting is serious, the locals can stifle /kill the local riffraff. I assume that every squad car has an automatic rifle and a 12 gauge shotgun in the trump —at least they used to.
Semi-auto rifle OR 12 Ga.
Rare to see both.
Cops also have side-arms and 20 - 50 rounds of ammo.
Against how many thugs?
Emotion may say Mow em down!, but practicality says that cannot happen.
And if it did what do you really think the results would be?
Try to think it through, no possible happy ending.
Response has to be limited to stopping the looting.
Store owners have every right to defend their property but cops shooting into a crowd would be disastrous for the nation.
That is why there are special trained police called SWAT TEAMS.
