The recent approach of cowering and standing by while rioters riot is a failure and only encourages more of the same. It is my opinion when a rioter engages in a deadly attack on law enforcement or public citizen that they should be shot and killed in self-defense. Were that to occur, at least those rioters will not try it again and maybe others will realize that trying the same would be a very bad idea. At the minimum, if not shot dead, they should be arrested, jailed, prosecuted, and then sentenced to very long jail terms. Even longer if anyone is injured by their actions.
All rioters and looters should be shot on sight. No arrest, detaining, trial; just shoot them.
Amen! Of course these anarchists are hoping for a martyr for their cause. Their goal is the destruction of the country. They must be stopped.
