Here's the reason for shooting the defecting, traitorous, provocateurs in the back - it's in the gol-danged Constitution, fer chrissakes:

Them Oaf Creepers ain't well regulated!
“You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.”
