Based on BATF's response I gather that this is not information that local law enforcement should be able to freely access. What the officer should have done is addressed the FFLs with a request for information on a specific gun or guns of specific serial number(s). The next step would be to obtain a warrant to follow up on positive hits or refusals. Where BATF would fall in on these two areas I don't know.Bottom line is that while I do agree with cooperation there is a way it needs to be done to remain legal and not to get yourself in trouble. Like I said before, if a law enforcement officer showed up at my door demanding to see my guns I would be on the phone to an attorney before they gained access unless they produced a warrant - at which point I would be on the phone to my attorney!
