I luve in a metropolitan area, one city is pro sanctuary but i cannot vote there. My suburb is sanctuary in practice, but not officially
My opinion is police enforce local laws, mugging, rape, .murder and all , leave fedwral law to the feds. Things like sneaking aliens out of jail to avoid ICE is wrong.
Individually i have liked the Mexican s i know, problem is mot the the world can move to US, or europe or down under. There are also non assimilated ghettos now
