Firing squad.
If congress had any balls, they’d put bounties on each of their heads. D or A, just like the old west.

So what about cruel and unusual punishment. These punks yukking it up and showing an attitude of “We did it. So what. We get out of jail after short time” need to have a shock treatment. The jury gives the guilty verdict, and they still have that “in yo face” smirk. How long will that smirk last when they hear death penalty, no appeal, to be carried out the next day with a flamethrower.
