Wait, why wouldn't bounty hunters be authorized to possess it? Isn't pursuit of someone who has a bench warrant exactly the kind of lawful purpose this is supposed to be limited to?
Bounty hunters are no different to you or I, in most places (and outlawed in several states). Some states require licensing as a PI. They have no connection to law enforcement (and due to abuses, many states ban any implication thereof, down to the color of vehicles used).
I think you are mistaking bounty hunters for law enforcement.
It's not the same thing.
They are more like loan sharks who require human beings as collateral.
They have no real affiliation with law enforcement. They also can't kick down your door or kill your dog like the police can.
Well they can. They're just much more likely to be held accountable if they do so without a really damn good reason.
Bounty hunters aren't law enforcement anymore than Luke Cage.
Because they are a private citizens and not law enforcement.
