nine handguns, a switchblade knife, a Taser, a set of brass knuckles, and night vision goggles. The vehicle was temporarily seized. No charges were filed for the weapons, as they were all registered and securely locked away, and Popper was licensed to carry them, with the exception of the brass knuckles and switchblade knife, which he agreed to surrender. A deal was reached that allowed the marijuana charge to be dropped if Popper remained free of further drug infractions for one year and attended eight hours of drug counseling.

Online controversy Popper is also known as an avid Twitter user and has caused some controversy on the platform.
