I have answered that question as "No!" and even "Hell No!" more than once. Yazoo City homeowner shot while attempting to protect his property | The Yazoo Herald.
Why are you paying for insurance?
A Yazoo City homeowner was shot Thursday night while attempting to protect his property from three individuals breaking into his vehicle outside his home.
What are you storing in your vehicle? Aside from my registration and proof of insurance and the owners' manual, I have a fairly generic first aid kit, a pair of jumper cables, an old winter coat and a pair of gloves. There may or may not be a flashlight, though since my cellphone doubles on that score I don't worry so much about that. There may be a few other things in the "emergency kit" aside from the coat and the gloves, but I wouldn't count on it. For a time I carried binoculars, but I never used them, and they were getting damaged, so...
Oh, and cooler, for when I buy frozen food. (It is a bit of drive to the grocery store.)
I could replace everything in my vehicle for about 100 bucks. The most expensive thing would be if they broke a window to get in.
As this story proves, being armed does NOT make you invincible. So what are you risking your life for?
Yes I know that there are causes worth dying for, and you have to be prepared to defend your life and the lives of loved ones, but risking you life for the spare change in your center console doesn't seem like battle worth fighting.
If you are storing valuable stuff in your vehicle you should either reconsider that, or find a way to park it in a secure garage.
And then you should still call 911 and wait as long as you can for the cavalry to arrive. "As long as you can" means until they threaten your safety.
