The judge and county attorney would likely be shielded by qualified immunity, in my opinion. The police chief who wrote the affidavit, executed the warrant, and ran his mouth on Facebook (he hasn’t run his mouth since the county attorney withdrew the warrant for insufficient evidence btw) while having potentially ulterior motives might not find it so easy, however. Qualified immunity generally shields incompetence, but not malice.

Edit: I will note as an aside that the hotel already had a liquor license, the owner just didn’t want to keep it under his name when the restaurant was the one running the bar.
