I'm surprised some people are against this. The way I read the petition, all it's saying is if I can carry on the outside of the installation gate, I should be able to carry on the inside. Obviously the gun free policy doesn't work. So not only can I not defend myself with a firearm while on post, I can't from the time I leave my house for the day until the time I get home since you can't even bring a gun on base (with certain very limited exceptions). The no guns policy is bullshit. I realize Joe can be dumb, I work with him everyday. Sometimes I even participate in Joe's shenanigans. But I'd rather take my chances being armed.
When I was stationed at Hood, I went through SRP about a month or two before Maj Fuckstick shot it up. I was TDY to Hood about 3 weeks ago. I could have easily been a target in either of the shootings. Chances are I wouldn't have been involved in either incident, and even if I was may or may not have been able to do anything, but again I'd rather take my chances with the means to defend myself.
This idea doesn't solve all the issues, but it's a step in the right direction. If I have a permit to carry concealed in CO, I should be able to carry on Carson or Pete or any other base/post.
