Sorry Rat, but you posting that article and then asking how NOT having a gun would improve the situation is pretty stupid.
I could post these articles and ask you to explain how HAVING a gun helped in these situations:
Father Accidentally Shoots Seven-Year-Old Son Outside Gun Store
YCSO: 12-year-old accidentally shoots, kills father

That point aside, why would anyone object to OFFICERS OF THE LAW having guns? Given recent events in Colorodo, its possible, if not likely, that if the intruder was armed, he was there to carry out a hit on them BECAUSE they were officers of the law. And if it was just a random burglary, the intruder probably did not have a gun or intent to cause harm.
Ultimately, neither side is going to change the others' minds. Lets consider two scenarios:
Scenario 1 - A law is passed outlawing all guns
Criminals would still have them. So some innocent people would die because they couldnt defend themselves from criminals. But lives of innocent people would be saved by eliminating gun-related accidents caused by members of their own family. Its a matter of whose lives you want to save. People are going to die either way.
Scenario 2 - Magically, you can take guns away from EVERYONE, good guys and badguys alike
Criminals could still kill you with knives. But on the other hand, its hard to accidently stab someone to death with a knife. So we're in the same situation. People are going to die either way - its a matter of which group you want to save.
THE only way to stop violence is to get rid of all the violent people. Dont send them to prison for a few years. Dont allow them to be a part of society. Get rid of them.
