Yes, California.
Hypocrites abound...
The sanctuary state of CA. *sigh* We really do need to just go under.....
The difference is that the California law applies post-arrest (subject in custody), but the Arizona law applies pre-arrest (stop and detain without an arrest), but based on reasonable suspicion. However, stops based on reasonable suspicion, without probable cause to arrest, have been around since the early 1960’s, when the SCOTUS decided Terry v. Ohio. In other words, SB1070 gives no new power to the police, but merely focuses it on enforcement of existing federal law, using existing authority and standards of constitutional protections.
