On the way from New York to Boston today, I encountered something new: the "Greyhound Security" desk. Here's how it works:
What all this is supposed to accomplish is beyond me. The cursory checks wouldn't prevent anyone from hiding something dangerous in his stowed luggage or even in the carry-on. Moreover, passengers not in the main line, or those who are in the main line but don't get checked before the bus starts boarding, are never looked at. I'll leave it to the reader to think of any of dozen ways that someone with bad intentions might bypass the check.
It's security theater, plain and simple.
And I guess that in this economy, it does have a possible benefit: it allows a few "security guards" to have a source of income. Which, of course, is reflected in the higher prices of bus tickets.
