I’d doubt ‘loaning’ is a valid excuse in California. The guns and sights...and trip to Saudi all seem very expensive to me, especially for a guy making $70k in California with a new baby. I wonder if he had an, ahem, benefactor from Trashcanistan or some place similar.
Unless you are standing right besides the person you loaned your firearm to at all times, loaning is illegal.
$50k not $70k as Environmental Inspector grading restaurants. Too much $$ for a job like that. Ridiculous.
