If so, you forgot some things:
1. The Police are not your friends (have a retired one in the family).
2. Never talk to the police without an attorney present ( have an active one in the family).
3. Police are not evauated by their bosses on how nice they are. Cases cleared and convictions obtained are their primary metrics.
"strip the gun", that gives you some idea of how many idiots can buy a computer without a basic I.Q. test !
Get an attorney, have him/her call BATF and get this resolved.
