Sort of reaching with those examples, aren't we? Nothing, no system, is perfect, but it can be better. A palm reader can be programmed for all members of your family, for instance. Bad guys usually go for cheap guns, either stolen or other throwaways. I'd doubt they'd go to the expense of getting a programmer. My suggestions would probably not solve all the problems with armed criminals, true, but something like that could improve the situation. Again, I have to point out that I do not think the OP was intended to start a debate on whether or not I can justify, to the rightys at any rate, my use of this site. I believe it was more a question of why I would put up with the garbage the extremists spew my way in order to use this site. I explained that. I don't care what anyone's opinion of those reasons are; that argument is for other times, other places.
