Take away their right to vote? It's for their own good!
More seriously, though, I'd love to talk to anybody who's changed their mind on this front, one way or the other. If you actually believe that giving up your own rights is a good price to maybe protect against rare events, what can make you change your mind? Related question: how many people changed their mind because they used to think "I have nothing to hide; I'm not doing anything wrong" and are now considered to be "doing something wrong"?
