A family in Sacramento, CA has put up aluminum barriers to radiation they allege neighbors are shooting at them. You have to wonder whether they're in need of psychiatric care, or just being joyously eccentric. Either way, I have no idea (never have, really) why governments should have the authority to tell someone to alter their property because it's "an eyesore." Is is a health hazard in this case? No: neither to the family, nor to the neighbors. Nor is it a cause of noise pollution so residents can't get to sleep. I say, leave them alone. Maybe send some social workers over to make sure there's not someone in danger of hurting someone else. But let the aluminum stay up. What will they do next, tell you you can't buy a blue car?
Peace,
Tor
