I thought maybe I was looking at a filter or net to catch potential tax cheaters that included inappropriate methodologies, but with the intention to catch tax cheats not punish political enemies. The reason that such a filter focusing on words like tea party, even if logically they might find fraud there, is inappropriate is that you can't distinguish an intent to punish from an intend to collect revenue that should be rightfully taxed. Even if the effort was revenue motivated, there is no way the paranoid will believe it. Democratic groups, I feel rather certain, would feel the same way if there were an influx of them pushing for dubious shelter with suspicion about the validity of many of their claims.
