Who's paying for it? Government? Then I unalterably oppose it.
Anyway, you're missing the point. Regardless of how you feel about government spending, Obama and his ilk have absolutely no problem making a whole bunch of anti-gun proposals that cost money. Cost is not an issue to them. So, given that cost is not an issue to them, why aren't they pushing something like trigger locks?
Heck, he's given enough speeches on the topic. Why isn't he at least using the free bully pulpit to encourage people to use them? That's the question to which I'd like to hear an answer.
