Scott,
Law Enforcement is not your strong suit, maybe a Barista at Starbucks cleaning out the needle bucket.
From what I remember, the sheriff and his deputies had visited his house multiple times and had plenty of opportunity to the charge him criminal offense which would have prevented his ability to purchase the murder weapon.
Does anybody remember how many times they were called? I think it’s funny he takes no responsibility yet allowed this Punk to walk time after time.
