Ok, figure bullets cost $1 each. Just for the sake of argument. Firing squad is usually 5 shooters, one has blanks. That's for the psychological impact, each shooter can say I had the blank, I didn't kill him/her. Here in NH it costs $38k a year to house a minimum security inmate. Maximum security is in the vicinity of $60k. That's more than alot of people make in a year. Hmmm, spend $1 and get it over with, or spend a few hundred thousand dollars to house, feed, and guard them. Or better yet, turn them all loose in the yard and let them fight to the end.
