but it's really not that difficult. Cops have residences and have plenty of contacts so falsifying a business reference is simple, anyone can do it. As far as references go, a good mind and some trickery can do wonders. But there's plenty of other ways too. If a specific agency or an Indy is targeted for whatever reason, they won't simply give up because you ask for screening info. If anything, it could make them more determined and less likely to show mercy, with the thought being that you're specifically trying to stop them from doing their job. As an agency owner, you have plausible deniability. But depending on how you advertise, that could be a tough sell.
Of course screening is a good tool to keep bad guys away.
