Exclusive: Gun lobbyist helped write ATF official's proposal to deregulate

After a police report indicated that this admitted killer was involuntarily committed to a mental institution were efforts made to include his name in the NICS data base?
We're efforts made to retrieve other firearms in his possession.
Why were the original charges initially dropped without any seeming provisions?
Did he purchase additional firearms after his initial arrest as a prohibited person?
Sometimes it's the rote things that are preventative.

Things heard around the office when the fingers started pointing;

"not my job"

"I'm only here about the 20 ga shotgun and extra ammo. I don't want to hear about any other guns"

"Brady disclosures would have been very embarrassing"

"that's a regulatory issue"

"Oh look the Daily Broadcast just came out; it's quitting time !!!

you can't make this stuff up...

I wonder if it "lacked prosecutorial merit", "not sexy enough" or "he ain't prohibited, I don't care what the FBI says..."

"...a family member had DiNardo involuntarily committed to a mental institution...he was barred by law from owning a firearm afterward. Nonetheless, when Bensalem police responded to a report of gunfire in February, an officer found DiNardo in his truck with a 20-gauge shotgun and extra ammunition...

Despite the mental health commitment and frequent interactions with police, DiNardo still managed to sell guns and marijuana in the area..."
