"You see, it’s expensive for every department to have its own SWAT team so several departments pool their resources and create what is called a “law enforcement council” or LEC. This is not an unreasonable idea. BUT! Some of these LECs are incorporated (presumably for tax purposes) and, according to them, that means they are a private entity that is not accountable to the public. I can’t imagine it would take much for these LECs to take the next logical step and become for-profit entities with private ownership."
