(the Vanishing 4th Amendment) TSA does surprise check at Lamar Boulevard Amtrak
/Random checks happen at stations across country --Once the train arrives, the dogs also sniff the cargo areas. 24 Jan 2013 Passengers catching the 9:30 a.m. Amtrak train from Austin to Dallas were met with an unexpected surprise when they got to the station. Transportation Security Administration agents, Austin police officers, and the Department of Homeland Security were all waiting for them. "These facilities are not necessarily protected as well," said George Robinson with TSA about bus stations and train stations that typically do not have the same security measures as airports. "We do impromptu visits at locations throughout the country."
