My bedroom directly faces my front door, which is equipped with one of those high-pitched sound devices if it's opened. (The whole house is wired as such.) That sound could wake the dead.

My .357 revolver is two feet away, and just beyond it is my Remington 870 short-barreled (but legal) shotgun loaded with 00 shells. I've got a clear view and have practiced what I'd do.

Alas, it's too cold where I live to have cacti, so I'm not completely safe.

There might be a business opportunity here: for plastic cacti with needles. Of course, these would do nothing to offset global warming, and might create a recycling problem.
