The inspections will take place when transit police determine that circumstances -- such as an elevated threat level -- warrant heightened vigilance. They will not be announced ahead of time.
I saw this and I wanted to scream a little: I see metal detectors and security lines in the future of metro. I get enough of that when I fly, thanks.
Here's my question: has an explosive ever been found on metro with intent to blow the trains up? I know that it's not a predictor for future behaviour but...really? Metro? I barely believe that they enforce the "no eating" rule anymore so how exactly is this going to work?
