People want the 'perfect' weapon.

They want something that will stop (100%) a seven-foot, 350lb guy on Angel Dust, but not harm or scare a child.

They want a gun that almost kills.

They want a weapon that will put a bad guy in suspended animation, but if he gets it away from them, he can't do the same to them.

IOW, people have been watching WAAAAAAY too much fiction.
