Unsure if he is a felon.
Unsure if they recovered the firearm. Videos are fine but without having the firearm it can be hard to prove it wasnt a replica.
To prosecute federally you have to show it traveled across state lines, so without knowing specifics of the firearm you cant prove it was made in another state. Looks like a Glock but they are made in different locations.
AND you have to have a DA or US Attorney willing to prosecute it. Cant see the DA want to prosecute their star "victim."
