I am a gun owner and a supporter of your right to bear arms. But the recent shootings have brought up the gun control/personal carry issues again. As a veteran, a former military cop, and trained extensively in the use of firearms my opinion on having everyone walking around armed is not as simple as both sides have made it.
I refer you to an article by fellow author David Morrell who posted a very good blog about guns on his website.
Those of us who have spent time carrying a firearm for work know the responsibility that comes with it and the training involved in making sure that you know how to handle situations when you encounter them. Take a read.
