One of the things to remember about a civil/religious rights lawsuit is that it's one of the few categories of civil suits where the plaintiff's right to recover punitive damages and legal fees is written into the law.
That would be US Code, Chapter 42 Section 1988.
I hope they get sued into oblivion. The stories I am hearing and reading about state that the worshippers are taking better precautions than folks going to the grocery store.
