. . . I missed this, @gano
I have no doubt Spector was "crazy". I don’t know if he was a decent human being before his decline/bipolar diagnosis, but being mean is not a crime. He should not have had a gun. (and I could go on about who else should not have a gun, and have my comment deleted)
but you are correct, he should not have had a gun, let alone as many has he did have. There is a BATF form (I just googled it and it is 4473) that has to be filled out and then a background check completed prior to successful purchase from a FFL dealer, and some of the questions that have to be answered correctly regard use of certain drugs, PFAs, felonies, and psych diagnoses. For some of these questions, there is a record that would come up on the background check, and for others, the honor system applies. I suspect a psych diagnosis might meet the latter criteria due to laws related to medical records and privacy. And then of course, there is always the straw purchase option. Someone with Spector's money and influence could have probably easily have paid someone to make the purchases for him. A lot of ways to get around it, which does mean that a lot of people that own guns shouldn't be allowed to.
