Aside from rioting, as already mentioned in a previous post, remember what happened in Mumbai a few years ago?
Justin makes the point well. A lot of folks seem to feel that a rifle in the trunk is a good protection against "rioting" or terrorist acts of some sort. And I'm afraid I still don't see how that's anything but a knee-jerk reaction. There doesn't' seem to be any real planning or analysis of possible positive reactions/outcomes involved.
If there's a riot somewhere nearby...what? Go out and get your rifle, and then come back into where-ever to hole up with your rifle? If you can enter this place with a rifle (during a riot) why didn't you have it with you before? And if you can, why would you? Get in your car and LEAVE! You don't want to shoot anyone -- even in a mob
scrutiny
and leaving is the very best way to prevent having to.
If you are driving and find yourself surrounded by a mob, do you think they're going to let you get out of your vehicle and go get your rifle? And if so...why? Why exit your 5,000 lb. weapon to go get your 10 lb. one?
And terrorism? First off...we just don't have a terrorism problem here. Even counting 9/11 (and the rifle would have helped, how?) you're more likely to be killed by bee stings than a terrorist act, and even world-wide, the vast majority of terrorist acts involve things like subterfuge and high explosives.
EVEN so...you find yourself in Mumbai and there's shooting going on. So what do you do with that rifle in your car? Try to get to it so you can go all "Bruce Willis" on them?
I know folks like to say, "well...having a rifle somewhere nearby gives me
options." But for all the realistic possible needs I've read, that rifle in the trunk might as well be a toaster.
So, someone get specific, PLEASE. Share a realistic scenario where you could use your trunk gun in a defensive way, and where a more compact, light, easy to carry, constantly-with-you, concealed handgun wouldn't do the job BETTER.
