“Either Arizona will never dare to push the law past the symbolic point, or else they will invite intolerable outcry and/or being overruled in Federal court.”
Do you think it’s possible that this law is just “window dressing” and isn’t meant to be actively enforced.
FWIW I think it will be overruled by the Fed. It’s going to appear too much like racial profiling.
The law has a codecil that allows the citizenry to sue an AZ LEA/county/city/town that refuses to enforce this. It is meant to be enforced. And enforced aggressively.
