In less than 10 minutes, 78 teenagers and young adults cycled through a 7-Eleven and emptied the shelves of candy bars, snacks and drinks. Before police arrived, they were gone.

The "flash rob" in Silver Spring last month was the fifth such mass theft in the Washington, D.C.-area since April, a crime trend defined by large groups of thieves descending on an unsuspecting store and quickly cleaning it out.

Howard County has yet to see any such flash robs yet, but officials say the department is aware of the phenomenon.

Police say the size and speed of the robbery crews make the crimes difficult to combat. Now, retail organizations and legislators in Maryland are pushing to increase penalties for flash robbers.

"Flash robs" were named because of their resemblance to flash mobs, where large groups of people connect with social media and meet in a public place to perform a song or a dance.

"It is not a flash mob, it's just organized violence," Staci Lawrence, co-founder of Flash Mob America, one of the largest flash mob organizations in the country, said of the robberies. "I don't know how it happened, but we really feel like the name was stolen from us."

But police say local flash robberies have lacked a key component of flash mobs -- they were generally not organized through social media.

The 7-Eleven heist in Silver Spring was not set up through websites like Facebook and Twitter, but "more of the old fashioned way -- word of mouth," said Capt. Paul Starks, spokesman for the Montgomery County Police.

"There may have been texting, but we have indications that some of the people who participated in (the theft) came from a young person's birthday party," he said.

Police originally thought a similar mass theft by about 25 people from a 7-Eleven in Germantown in August was organized through social media. But they later learned that the plan was hatched by suspects during conversations at the Montgomery County Fair.

In Howard County, a spokeswoman said the key to tracking flash robs is through preparedness and communication.

"We have an operational preparedness division that works with other jurisdictions so when there is a trend like the flash robs… we can share that information with our officers on the street," said spokesperson Elizabeth Schroen.

"Being in a relatively small jurisdiction, some of our officers are familiar with a lot of the repeat offenders," said Schroen. She says she doesn't know whether tapping into these relationships or digging into the local social media would realistically help stymie the events.

"This type of situation is somewhat difficult to predict," said Schroen, adding that typically a robbery leads to a review of surveillance cameras, identifying suspect vehicles and locating suspects who could lead to others involved.

Schroen said the department has not done anything in particular to prepare for a flash rob, but that the department has a unit that helps communicate trends that appear to be coming to the county.

D.C. police, who have also had to deal with some thefts labeled as flash mob robberies, said they have no evidence that social media was used in any recent group crimes, spokeswoman Gwendolyn Crump said.

And social media may not play a huge role in organizing most mass thefts in the country.

A survey conducted by the National Retail Federation in July found that more than three-quarters of the retail companies surveyed said they were victim of mass thefts. However, only 10 percent of those companies reported to being victimized by "flash mob tactics" -- crimes organized through social media -- in the past year.

Whether criminals use social media or not, retailers and legislators are looking for harsher penalties for flash robbers.

Delegate Jeff Waldstreicher, D-Montgomery, plans to introduce a bill during next year's General Assembly that would charge each member of a flash rob crew with stealing the total value of all the merchandise stolen by the group, rather than what each personally took.

Pat Donoho, president of the Maryland Retailers Association, an organization representing more than 600 retailers in the state, favors the change, which could turn misdemeanor crimes into felonies.

"You have a situation where right now you need to steal $1,000 for it to be a felony," Donoho said. "If 10 people walk out with $500 individually, that's not a felony. If they get prosecuted by the total value of all the merchandise stolen, they all could be charged with a felony."

Still, Donoho said, his organization does not see flash robberies as the most pressing security concern for stores.

"We are not overly concerned about it, but it is a very real phenomenon, for lack of a better term," he said.

To catch flash robbers, police are turning to social media sites like Facebook, YouTube and Twitter for help.

Montgomery County Police posted security footage from both the mass theft in Germantown and Silver Spring on YouTube to help identify suspects. Starks credited the videos with the arrest of 17 of the suspects from the Germantown crime.

The security footage of the Silver Spring crime had close to 400,000 views on YouTube as of last week.

Aside from using social media to combat flash robberies, Starks said retail managers and employees can protect their stores by calling the police as soon as they suspect a crime is about to occur.

"If you feel uncomfortable, go with your gut," he said. "Call the police, let us come out, because once it is occurring, folks can dial 911 but there is a given response time and the way these things occur it can end quickly."
