(WJLA) - Most stores these days have surveillance cameras inside - like this True Religion store on M Street in Georgetown.
But that didn't stop a group of teenagers from walking into the shop for a flash mob robbery.
In this video, you can see several people clearly take merchandise off the tables and place it into a bag.
"They walked in and just picked stuff up and took it," describes shopper Jessica Almaas. "That's odd for M street...Stuff happens maybe later, but not at 6 p.m."
The theft happened last month sometime in the evening, and remarkably, the thieves didn't even try to hide their faces. They walked in together in what's known as "flash mob style."
"Wow, that's crazy. That's hard for a shop that only has three or four employees to handle that many people," says shopper Alex Grymes.
Many stores in Georgetown employ a security guard who stands by the door, but True Religion declined to comment on its security procedures.
"It may be apparent to them that there's lack of security and they can easily get away with it if they do it quickly and in numbers," says shopper Brendan Gilbert.
