What's wrong with the occassional bar raid? Happens all the time in Europe with raids for drugs. They do this because drugs are illegal. Likewise here, homosexuality is illegal so they raid the gay bar.
Been a while since the last one I remember which was at the nightclub (now shut down) above what was Fibbers (now shut down) for a gay night, when the infamous Mr Miles the DJ was arrested and sent packing pretty quickly.
You can get away with pretty much anything in this country so long as it is done discreetly. Most people know where the line is and it is up to you as an expat to research the laws of the society you are living in. I would think most people with their cars conviscated deserved it. They need to clamp down harder in this area.
