Occupy Oakland activists posted online the phone number and address of the officer thought to have wounded Iraq War vet Scott Olson last week. Trouble is, they weren't really his.

The brutal injury suffered by an Iraq War veteran during the police crackdown on the Occupy Oakland camp last week has become a rallying cry for supporters of the global movement to protest wealth disparity throughout the world. But Marine veteran Scott Olsen wasn't the only one hurt in the aftermath of the violence at the Occupy Oakland camp, PCMag has learned.

Two San Francisco men found themselves threatened and fearing for their families' safety last week when Occupy supporters posted their contact information onlinewrongly believing it belonged to a police officer accused of firing the tear gas canister that fractured Olsen's skull and put him in critical condition.

"They started calling around Thursday or Friday," said one of the men, who said he'd received dozens of threatening phone calls in the past week or so. The source said that when calls started coming in at 4 a.m. from Texas, New York, Massachusetts, and elsewhere, he took the phone off the hook and started to become very concerned for the safety of his wife and young daughter.

Olsen is expected to make a full recovery. The two men, both bartenders at San Francisco bars who spoke to PCMag on condition of anonymity, have also taken steps to protect themselves from harassment and possible physical threats stemming from online vigilantism gone very wrong.

Last week, some people associated with the Occupy movement and the Anonymous hacktivist collective claimed to have identified the officer who injured Olsen as San Francisco Sheriff's Department deputy Scott Bergstresser, based on amateur video of the crackdown (below).

Officers from the San Francisco Sheriff's Department and Santa Clara County Sheriff's Department were on hand to assist Oakland police and Alameda County Sheriff's officers during the crackdown on the Occupy Oakland camp.

To date, it hasn't been confirmed that Bergstresser was the officer who hurt Olsen, who can be seen in the video lying prone near a police barricade as other Occupy protesters rush in to help him, only to be dispersed by a flash bang grenade fired by police just seconds later.

San Francisco Sheriff Michael Hennessey and a Santa Clara County Sheriff's Department spokesperson have said that their riot control units did not have tear gas, rubber bullets, or other projectiles used in crowd control on the night in question. The San Francisco Sheriff's Department did not immediately respond to a request for comment.

UPDATE: A San Francisco Sheriff's Department spokesperson told PCMag late on Thursday that Sheriff's Deputy Scott Bergstresser was not responsible for Iraq War veteran Scott Olsen's injuries. "It wasn't him," she said, reiterating San Francisco Sheriff Michael Hennessey's earlier statement that San Francisco Sheriff's officers at the Occupy Oakland crackdown were not carrying tear gas canisters or any other crowd-control projectiles, including flash bang grenades.

The Dark Side of Online Activism As Bergstresser's identity became the subject of discussion on Twitter and other online venues, some Occupy supporters cautioned others to make sure he was the officer responsible for injuring Olsen.

But that didn't stop some people from publishing what they believed to be Bergstresser's street address and phone number on Olsen's Facebook page, OccupyTheNation.com, Pastebin, and elsewhere.

The trouble is, the street address they posted belongs to one of the men we spoke with, while the phone number belongs to the other. Neither were anywhere near the Occupy Oakland camp on the night in question, has anything to do with law enforcement, or even knows Bergstresser. But they were housemates at an apartment rented years ago by Bergstresser, who left about three years before they moved in. One of the men still lives there, while the other took the phone number associated with the land line there when he moved out, they said.

So-called "dox" posted online that listed several street addresses and phone numbers supposedly associated with Bergstresser include the San Francisco address of one man and an area code 415 number that belonged to the other. More than a dozen street addresses are listed in a "final dox" on Bergstresser seen by PCMag, as well as four telephone numbers, an email address, Facebook profile, and the names of several people whom the poster claims are the officer's relatives.

The man who received the threatening phone calls said he was able to track down one repeat caller from Austin, Texas, who was identifiable by Caller ID. He has since changed his phone number and filed a police report, though he doesn't hold out much hope of anyone being caught because so many of the calls came from outside the local police jurisdiction.

"At first, we didn't know what the hell they were looking for," the source said, describing the beginning of the harassment. "They kept saying, 'We're looking for Scott,' and we pieced it together because we used to get mail addressed to him at the old place. We'd say, 'He's not here,' and then they started saying, 'What, is he hiding out?'"

The other San Francisco man, who still lives at the address that was published online, said he hadn't been threatened as of this week, but he did ask police to swing by his street periodically after learning what was happening from his former roommate.

Both men, who tend bar at nearby watering holes catering to a neighborhood crowd in the Haight-Ashbury district, said they still supported much of what the Occupy movement was doing, despite finding themselves caught in the crossfire.

"But they are starting to kind of p*** me off," said the man who received the threatening phone calls.
