Not sure what your point is. Bounty hunters and private groups have been around for the history of the country, and will as long as the money is there. Are you trying to link this to the perceived need for state militias over and above those that already exist in each state?
Yes!
Just as I proposed to the U.S. Coast Guard the creation of an armed U.S. Merchant Marine Auxiliary modeled after the unarmed U.S. Coast Guard Auxiliry. A proposal that fell on deaf ears and blind eyes.
