The arrest of Elvira Arellano has been in the news, and I heard on the radio that there is no such thing as sanctuary, that the police can go anywhere to arrest anyone.
Is this true? If so, why did they wait a year to arrest Arellano? I remember seeing one of those Shocking Video shows where police actually walked into a church, interrupted a wedding in progress, and hauled off the groom in handcuffs (he was wanted for armed robbery or something.) Or is there a legal definition of sanctuary in a place of worship?
