You are aware that many large breeders will feed live rodents to hundreds of snakes a week, right? I feed a couple of my picky snakes live rats and have for years without one incident. I'm pretty sure that most snakes in the wild eat live prey as well.
Sure, accidents do happen, but they can with F/T prey as well. People will fail to thaw out the rodent or over cook it which will lead to a whole different set of problems for the snake.
As with any type of feeding, it's the responsibility of the owner to feed their animals correctly.
