I don't live in Anchorage. I keep my airplane in front of my house. Even there it is a risk. I have a security light and a bell that rings in my house when something  moves near my airplane. What give you the stupid idea that I should stay "up all night in a chair" protecting other people property? Owning property is a risk, you think it is my job to protect others property or are you just an argumentative jerk? If I had my way there would be more prisons and police. However when there are more police they just seem to be interested in writing tickets for revenue. I had a vandalism incident once, I called the Troopers and was told "we don't have anyone we can send out. I think Thor Von Wolfrun is correct, it is the FBI that investigates aircraft crime, I didn't want to say it as I am not sure. I feel bad for the people who's planes were vandalized, and would like to think that the miscreants will be apprehended, given appropriate punishment, and restitution would be made, but I doubt.
