People are overly distrustful of private entities. Likewise, they're also overly trustful of public entities. It's implicit in almost every argument you will have when advocating free-market solutions over state-monopoly and state-regulation type solutions. And this applies to practically any problem.

Unfortunately, no one wants to see the elephant in the room. Both types of entities will do (or at least have the risk-of doing) what is in their own best interest. But only one can have a violence-backed monopoly advantage.
