The police aren't there to protect you. They respond to calls after the incident happens. I called the local sheriff's dept. regarding my incident while I was still in the parking lot. Turned out the city had finger-annexed that site and I would wind up having to talk to the city police. They don't even patrol out there, because that little section of road is the only part that is in the city for about 6 miles.
I wasn't saying anything regarding the handicapped situation. I'm talking about road rage. Incidents that happen on the road. When it comes down to it, if I see somebody park in a handicapped space I'll notify management. Oftentimes that either gets the person spoken to, or gets their car towed/ticketed.
I don't know how this conversation turned the corner to peeping toms, though.
If you have somebody outside your window call the police. Request that they come quietly and try to catch the person in the act. If you can find evidence that someone is outside your window, do it. You can even put thorny bushes outside the window, if possible. No peeping tom wants to stand around in all his glory while a holly bush (or bougainvillea, etc...) is poking him in the backside. Put lights up if possible. Call the utility company and see about having a light installed. We have one, and it costs us about $10 more a month, IIRC, and the utility company installed it.
Dragging them into the house is an old wives' tale that will wind up getting you in trouble. Technology is such that they *will* know where the perp was at the time.
Try having someone stake the outside out and catch him in the act. If you are in fear for your life or imminent, grave bodily harm, in my state lethal force is permitted, and that fear is a valid defense. Your state may vary. That said, you *will* stand trial, and you *might* be acquitted, so make sure you are sure that the threat is that severe. IMHO, a peeping tom does not warrant that kind of force.
There are some *seriously* messed up people in this world. If I worried about all of them, I'd never have any time for myself.
Barring all that, get really good blinds, or even a blanket that covers the entire window. An ounce of prevention is worth a pound of cure.
