The other death penalty poll made me think of this.
Do you think support for the death penalty would change significantly if we as citizens had to be the ones to actually kill the inmates? For example, any time a state killed an inmate they would hold a lottery with the names of all registered voters in that state, and the person's name that was drawn would be the one to have to carry out the death sentence. Obviously they would have help with the technical aspects (for example, a nurse/doctor/medic to insert the IV), but they would be the ones to push the button.
Let's assume that failing to perform your duty as required would get you charged with a misdemeanor.
