Hialeah passed four ordinances in 1987 and the word Santeria appears in none of them. A law that names its target can be attacked. A law that does not has to be caught.
The prohibition is one word wide. It forbids sacrifice, then defines sacrifice as killing an animal unnecessarily in a ritual not for the primary purpose of food consumption. Somebody has to decide what is necessary. The Supreme Court found out who had. Hunting is necessary. Killing rats is necessary. Putting down a stray is necessary. Worship is not.
The ordinances fell in 1993. The congregation won, and the instrument was never confiscated. It takes a word like unnecessary, exemptions long enough to look even-handed, and patience.
