Maybe they should go back to hanging.
It works, and it's fast.
I have said for years that however someone kills another person is how they die... and televise it. If they burn someone to death... they get burned to death.
They shoot someone in the gut and that person dies... they get gut shot... and put it on TV.
They starve someone to death, they get starved to death.. and televise it.
I predict only about 1 or 2 per state would have sentence carried out and I predict a murder rate of near zero in under a year.
