Inside the house, it sounds like they found small amounts of marijuana and a white substance. Doesn't sound like they were dealing drugs. The guns they had were a revolver and shotgun. Again, not the kind that drug dealers generally use.
I'm trying to find out, but they said they were undercover officers. I'm trying to see if they were uniformed or not.
