Bible is clear that Gods laws are more important than any of mans laws…to try and justify the opposite seems wrong. I think alot of christians today are guilty of worrying about mans laws before Gods, alot of churches too.
Think about it, in protection of an abortion clinic, doctor, or patient, law enforcement thinks nothing of showing up in force, armed to the hilt and will use force if needed. IMO, the opposition should be equally ready to stand up for what they know is right.
