Madison County Sheriff's Office Capt. Mike Salomonsky tells local news outlets the video led investigators to serve a search warrant Tuesday morning at a Huntsville home.
The search turned up two handguns, a shotgun, a rifle and marijuana that appeared to be packaged for sale.
Officers arrested 23-year-old Terry Martez Brown and charged him with drug paraphernalia possession, loitering and promoting prison contraband.
Also arrested was 49-year-old Kenneth Fennell White, who's charged with first-degree marijuana possession and being a felon in possession of a firearm.
The video has been shared 86,000 times since it was posted to Facebook on Nov. 9.
It's unclear if Brown or White have attorneys.
