Not having read the ENITIRE thread, but I swear, some pro-gun people act as if they live in the middle of a war zone. The odds that the average person will need a gun for protection are lower in places with gun bans, and having one may end up being worse than not having one. That said the odds that the average person will need a gun for protection in places that allow guns isn't much higher than without. Either way the odds of the average person needing a gun for protection are pretty low. Arming "innocent" people isn't going to make anyone safer. It may cause petty crime to decrease, but won't have much affect on intentional violent crime (in other words, a mugger most likely wouldn't kill you unless provoked, so might not mug you if he thinks you are armed. But if you are specifically targeted, it won't stop him).
Pro-gun people act as if in the good 'ol days people walked around packing heat...well it was illegal at the founding of our country so it should be now. We had no national military...the average citizens needed weapons in case the country to went to war or there was an uprising. They had the added benefit of protecting ones home and hunting for food. The idea that you need to travel around the country with one is ridiculous, and you most certainly don't need to bring one with you to work.
Yes there are bad people out there. No gun bans won't stop them from using guns. But ordinary citizens cannot be trusted to do what is right. Unfortunately there are bad people in this world who are going to always do what they do. Arming the citizenry isn't going to stop them. How long before we hear about teachers shooting students in Texas because they were reaching for a cell phone but the teacher thought it was a gun?
