I’m inclined to give this the benefit of the doubt

Based on the information given, I am not.

The media loves to sensationalize stories like this.
If someone randomly arrested me, they would talk about the "...thousands of rounds of ammunition..." found in my house...as if that means anything.
The guy wanted to purchase a sweet new Heckler & Koch and there is no crime in that. In fact, mine reside nicely next to my various Sig Sauer pistols.
Somebody will hopefully get their hand smacked HARD for this absurd action.
