Sorry, but that was one of the least helpful things I have read in a while. The guy claims to be rousted by the cops for buying ammo from some broker online, and he repeatedly warns against doing this, but then doesn't ever say who it was, only noting he has many listings. Fat lot of help that would be to fellow New Yorkers.
The really funny part is how he is so concerned that the cops now have his personal information, which they got from his vehicle. I am pretty sure that the cops already have access to a person's DL, ID, vehicle information, gun records, etc. They did not need to interrogate this guy to get any of that information.
My guess is that there is a lot more to this story than the naïve ramblings posted.
