I'm sure hundreds of lives were saved by this, thousands even I bet. It's not like someone can just go out and build themselves a rifle or pistol these days in their family room or something without a background check. Bless those police that used our taxpayer dollars to fund this highly impressive operation.
I have zero problems with this arrest. Scumbags like this give legit gun owners a bad name. Scumbags like this are the reason we're constantly defending ourselves against the anti-2A crowd.
