That could be the case but it also has to do with reported crime on their premises (including parking lots). Those are the two main reasons I've seen.Usually you would find out later that someone had lodged a complaint about that club.
My ex-partner is married to a TABC agent and I run across him and his squad a couple of weekends a month. They always have a list of clubs & bars they want to hit that night along with any addition recommendations that we might provide.
