What is telling is how quick folks like you are to throw the law and the COTUS under the bus while joyfully embracing authoritarianism. Those are not things that Americans would do.
I've always been pro summarily and/or pre-emptively executing foreign terrorists. Also rounding up criminals and throwing them in jail is absolutely productive. If they resist or otherwise assault law enforcement - thne let them bear the wages of their sins. Criminal predators do not deserve to walk free and the notion that these violent habitual offenders can ever be 'rehabilitated' is nonsense. It is apparent while they are still in school which ones are sociopaths. It is absolutely easy to spot them. Normal, mentally healthy people do not rob, rape and kill. Those that do forfeit their rights and citizenship.
