If I'm not mistaken, a police oficer must place his hand on the Bible and swear an oath (to God) that he will uphold the constitution of the United States of America. Those police officers were in direct violation of that oath when they entered that church, for the Constitution protects freedom of assembly, freedom of religion, and freedom of speech.
Those officers need to take a stand against thier superior officers and refuse to break thier oath to uphold the Constitution.
