Another good case for gun control
I am curious as to what you mean by "gun control". Do you mean disarming the populace of the US? Do you mean stricter controls on who buys what, such as in Canada? I am at a loss as to how "gun control" would have made a difference in this case. It seems that the husband wanted her dead, a gun was the tool of choice this time. If he had not had the gun, I beleive he would have found another way to kill her.
So you can see where my feelings lie, a gun is nothing more than a tool, I have guns and I have yet to see one of them do anything on their own. They are inanimate objects, incapable of leaving the safe and causing harm on their own.
Yes, the US has it share of firearms violence, yet so do many countries with laws prohibiting or severely restricting gun ownership.
I am not sure "gun control" is the answer, esp. in the US. There are already thousands of laws on the books to regulate guns, yet very few are enforced. So, rather than try and force more control onto us, I feel the just the opposite would be a better alternative. Less control for law abiding citizens, after all, I believe Robert Heinlien said it best when he said "An armed society is a polite society."
