FYI Simple... In the state of Washington is IS NOT legal to use deadly force to protect property. You can use it to protect life just not property.
I ran into this awhile ago while I was standing in my doorway (.40 Glock in hand) watching a guy smash out my car window while I was on the phone with the cops.
While the end result was gratifying (I watched the cop chase the guy down the street, then taze him in the neck) I still will not be reimbursed for my car being jacked up. He broke out a window broke both door handles and bent my drivers door. He plead guilty and got 22 months because he had a huge knife and a bb gun tucked in his pants. They said payment could come after he got out and got a job. Yeah so 3 years from now I might see some money. (SHOULD HAVE STARTED A FIGHT AND SHOT HIM, THAT WAY IT WOULD HAVE BEEN MY WORD AGAINST WELL.. NO ONES
But just wanted to make sure that everyone checks local state laws before using deadly force. And to the origional poster. Get cameras! Best way to catch someone and prove it.
