It's been a long time coming but the Supreme Court has actually decided in favor of the Constitution's second amendment. The ink is hardly dry on the decision and there's lawsuits springing up all over the place. Enough so that I doubt the lawyers will need to spend much on marketing pens & such... they'll be too busy arguing every side of the issue.
The way I see things is that the gun control side wants to cut crime by making it harder to legally buy and own guns. The problem with this theory is that all this gets done is make sure that law abiding citizens don't have guns. The criminal element on the other hand well, I am not a hamster, they're going to have the guns anyway.
As for handguns (and other firearms) in homes being available for somebody to use them for suicide and / or mayhem and murder if somebody snaps... well, really, You could say that exact same thing about steak knives.
They're dangerous, they can be (and have been) used to commit suicide, mayhem and murder. Yet nobody's trying to organize a "steak knife control lobby" and try to pass "steak knife control laws" requiring people to get permits, undergo background checks and waiting periods to purchase a steak knife. I've got a knife with a ten inch long blade in my kitchen, would it be legal to own it under such laws? I hope so, preparing meals is SO much easier with it.
You could also make similar arguments about a lot of common household items and in the end you get the same result, [insert weapon of choice here] doesn't kill people, people kill people. The solution is not banning weapons, but in educating people and requiring everyone to think and act responsibly.
