Bradley County (Cleveland,TN) is a very motivated area and lots of people here wanted to be involved and no doubt the BCSO felt they had something to offer. If it were my child lost out of state I'd be thrilled that hometown forces tried to help, and if egos don't get in the way, I would think more professionals would always be welcome by an investigating agency.
I don't think incompetency was insinuated at all.
Incompetency has been more than insinuated on the Find Joe Keller Facebook page, but *perhaps* not by the BCS, himself. Does it make sense that there are pre-existing structures in place for activating inter-agency cooperation precisely to (among other things) prevent the emotions of otherwise structurally uninvolved law enforcement officers and their constituents from interfering with the methods and actions of investigation? Procedure is not ego, but adherence to procedure has motivated a lot of insinuation. _IMO_
