When federal Bureau of Alcohol, Tobacco, Firearms and Explosives agents showed up at a warehouse complex owned by Harold Chapman, he gave them the keys and offered to show them anything they wanted. But Chapman, who has previously allowed local police to use the complex for training exercises, says they still knocked down doors and caused $1 million in damage. All they took with them, he says, was a few documents and some machine parts. The warrant for the search is sealed. But the San Francisco Chronicle reports agents were searching for "military weapons and explosives." Chapman says to his knowledge he has no weapons or explosives. But he often buys items at government auctions. "Some of the stuff they sold me is in sealed boxes that we still haven't had time to open…So if there's anything illegal in here, it's their own damn fault," he told the Chronicle.
