I believe all the incidents involve Maryland Transportation Authority Police. The article states one officer is involved in two separate stops. I want to point out the Maryland Transportation Authority Police are a special unit tied to DHS because of the tunnels.
We know that the FBI and the ATF constructed an illegal data base of gun owners in the late 90’s and were told to dismantle the data base by Congress. It would come as no surprise if the data base was never destroyed. Both agencies now come under the direction of the DHS. Obummer certainly is not concerned about following the law and his appointees run all the agencies.
