Re: There's one way to stop this
You're thinking of summery executions. Death penalty almost always involves a lot of trials and appeals, almost always costing more than keeping someone in prison for life.
So either you have a system where people are getting killed for things they didn't do, or finding very expensive ways for the state to kill it's own citizens.
But it's a pretty typical narrow minded little englander attitude, written by someone not near enough to the bottom or top of society to actually appreciate how the law does (or doesn't) work, and especially on how it's enforced.
I'm sure you'll be voting for whoever is offering to reduce our freedoms in the name of fighting $Enemy, who hate us because of our freedoms, and nothing to do with killing and theft.
