Arizona taking away constitutional rights?

[Riot]

is this really that difficult a crime to investigate? what makes it so special? feds want you, they turn you over...u.s. marshals, same thing. state wants you, the locals hold you til the state comes and gets you....so what's the big deal about this?

All law enforcement agencies are not the same, nor do they have the same jurisdiction and powers. I don't want my local sheriff investigating me for income tax evasion - do you?

Turning someone over to a different jurisdiction when there is a want/warrant already out for their arrest is NOT the same thing as initiating an investigation into a possible violation of federal law by a local law enforcement agency who does not hold federal jurisdiction.

Currently, if a local cop suspects you of violating federal law, they contact the appropriate federal agency: US Marshal, FBI, etc. They do not do any investigation or arrests on that level independently.

Seriously - I find it simply terrifying that any local yahoo sheriff, any cop on the street in Chicago, or a one-horse town in Nebraska, etc could independently - without contacting the currently appropriate authority - initiate a federal investigation into a violation of federal law. RICO, federal income tax, etc. Talk about Big Brother, big government, loss of personal rights and freedoms!
