Can they get an "anticipatory" warrant to search my house just because a gun I own matches a caliber of a gun used in an area crime?

No, the "anticipatory" part refers to them having some proof that a crime is going to be committed.

I have no doubt that some leftist judges would issue them a regular warrant based upon the caliber match alone since there's no reason that an innocent man would own any sort of gun (to the leftist way of thinking, anyhow).

Yeah... that is pretty much how my mind played that scenario out as well. That ownership becomes prima facia "probable cause" despite a lack of intent or action.

Doesn't fit the case in the above as both intent and action are there, but I could see this ruling used as amicus to futher twist it to give "law" enforcement an all to easily corruptable means to targeting an individual.

Most likely, I'm just being paranoid.
