The behavior of a city, county or state not adhering to lawful federal laws cannot be allowed. This is the proverbial "slippery slope." The proponents of sanctuary cities are blind to the precedent they are setting. How will they feel when there are abortion-free cities or cities who refuse to follow EEOC mandates, etc.? They need to follow the right process, which is to have Congress change the legislation, not to try to do it by themselves!
