Spotted some good, sensible security on the DC Metro (part surface, part overhead, part underground metropolitan railway) yesterday. Apologies for the bad picture quality, but I was trying to take the photo without getting arrested for being a terrorist (the irony)…
The text reads:
Hey, is that your bag?
If you see someone leave something on a bus, in a train or station, kindly ask them “is that your bag?”.
If they don’t take it or if you see an abandoned package, please contact a Metro employee or police officer immediately.
No need to shoot someone for leaving their bag behind. 99% of the time, it’ll be a real left-behind-bag. Treating it like that is good security.
