The reporting is always so idiotic on this incidents. A 50 pound bag of fertilizer becomes 'powder'. They weren't just handguns, they were 'heavy-caliber handguns'. They cite 'long guns' as though they are a new, more deadly firearm. And, of course we have the obligatory 'few thousand rounds of ammunition'.
The guy doesn't sound like a saint, but it sure seems like a lot of exaggeration.
