MARTA has filed a brief in opposition to GCO’s motion for summary judgment in GCO’s federal lawsuit against MARTA for MARTA’s policy of detaining anyone seen carrying a firearm. While MARTA now concedes that GCO member Christopher Raissi was detained when two officers stopped him, disarmed him, and ran a background check on him, they argue that it was not a 4th amendment violation to do so because MARTA is a terrorist target and high crime area. For MARTA’s explanation of why the 4th amendment does not apply when one steps off the Atlanta sidewalk and into the Five Points train station, see the briefs here.
