Remember the days before Sept. 11, 2001, when people complained endlessly about delays at airport security lines?

Well, that good, old-time Sept. 10 carping and complaining may be ready for a comeback.

New York City authorities are instituting a random bag-check policy inside its public transit systems; here's the initial response from Jen Chung at Gothamist:

Dude, this is opening up about a thousand incidents where people freak out when they see their train coming in and the NYPD is checking is a bag.

New Yorkers have coped with National Guardsmen holding automatic weapons and standing watch over Penn Station. They've coped with major changes to city traffic patterns because of security reasons. Heck - they've coped with all porno being taken out of Times Square.

Not only that, but Yankee and Met fans have been subject to random bag searches for years as they enter Yankee Stadium or Shea Stadium. And the freakouts have been pretty much kept to a minimum.

The big question isn't why city officials are choosing to randomly check bags, but why it's taken so long.
