Can you please explain how your "Common Sense" applies to the case at hand?
Sense you said please...
Hand guns are too easily concealed, along with open carry laws there is a real danger of guns not protecting you or your family, but putting them at greater risk - not necessarily from you, but from others untrained or with evil intent.
Your side argues having a firearm makes you safer, and that maybe true. But, it seems not to make us, as a society safer, given the number of homicides, suicides and accidental deaths caused by firearms.
Will this decision mean that cheap handguns will now be for sale at Wall Mart? Best tell your kids and remind yourself the next time someone cuts you off on the road, to ignore them; for flipping them the bird or even looking at them with 'disprespect' may result in a violent response (hyperbole, maybe, but less than Condi Rice or Dick Cheney or Bush II suggesting not invading Iraq might result in a mushroom c loud).
I have no problem with someone having a firearm in their home for protecton. That said, an untrained person in a stressed state is less liikely to hit a threat with a handgun - especially a high powered weapon - and the potential for collaterial damage is great.
My greater concern is the Roberts Court has become extemely ideological and partisan, and is clearly what you conservatives feared - activist.
