According to WTOP via Slate, this week’s foiled terrorist plot (though how much of a plot is some video and a diagram you could get from any metro station?) may have Metro Police starting random bag searches of riders on the system. I’m not sure how random searches are going to do anything but scare people and/or piss them off, but since Metro has been ignoring general safety for some time, I guess they’re planning to scare people into not using the system another way?
Use your head, WMATA, don’t do this. This is just a joke posing as security.
