As pointed out above, no one is having a pop at responsible gun ownership. It's the irresponsible gun owners that are the problem.
Just like with motor vehicles proper testing and licensing can't stop every incident but proper regulation and training plays a big part in all of our safety as a society. Many on this forum complain that licensing and testing isn't strict enough for vehicles due to their safety being put at risk with bad drivers. That is exactly how I feel about gun control.
