 (Reuters) - Police officers in Ferguson, Missouri, have begun wearing body cameras after weeks of unrest over the shooting death of an unarmed black teen by a white officer and sharply differing accounts of the incident, officials said on Sunday. 
  
 Michael Brown, 18, was shot multiple times by Ferguson Police Officer Darren Wilson on Aug. 9, sparking nearly three weeks of angry protests in the St. Louis suburb and drawing global attention to race relations in the United States. 
  
 Law enforcement and witnesses gave differing accounts of what transpired before Brown was shot, with police saying the teen had struggled with the officer. Witnesses say Brown held up his hands and was surrendering when he was shot multiple times in the head and chest. 
  
 The discrepancy has revived calls for officers across the county to be outfitted with body cameras to help capture an accurate record of police-involved incidents. 
  
 The policy has the support of scores of law enforcement agencies and the American Civil Liberties Union. Opponents say the cameras could be an invasion of privacy and deter people from approaching police with a tip. 
  
 During protests on Saturday, Ferguson officers began wearing small body cameras clipped to their uniforms that recorded crowds, conversations and even some taunts by demonstrators, a police official said on Sunday. 
  
 Ferguson Police Chief Tom Jackson told the St. Louis Post-Dispatch the cameras have been well received by officers. 
  
 "They are really enjoying them," he said. "They are trying to get used to using them." 
  
 The cameras were donated by two video surveillance companies, Safety Visions and Digital Ally. In a statement on its website, Safety Vision said it donated the cameras in the hopes that they could bring transparency to future investigations. 
  
 "The city of Ferguson has gone through an unfortunate series of events and Safety Vision body cameras and flashlight DVR will assist in capturing prima facie evidence for investigations involving vandalism, looting, and shots fired," the statement said. 
  
 Some stores were looted in nightly protests, and police responded with riot gear and moved in military equipment to try to quell the turmoil. 
  
 A St. Louis County grand jury has begun hearing evidence about Brown's killing and the U.S. Justice Department has opened its own investigation.

 The forecast translates into a 26.4 percent jump in revenue from $17.8 million in 2013. 
  
 The fatal shooting of an unarmed black teenager in Ferguson, Missouri, sparked demand to hold law enforcement officials accountable and in turn fueled interest in companies such as Digital Ally and Taser International Inc. 
  
 The company's 2014 revenue forecast was first reported by USA Today on Thursday, citing Chief Executive Stanton Ross, according to a regulatory filing on Friday. 
  
 Digital Ally said on Thursday it had received its first camera order after the Ferguson incident from the Michigan police department. 
  
 The company's shares closed at $18.66 on Friday on the Nasdaq. 
  
 Up to Friday's close, the stock had risen about 387 percent since Aug. 8, the day before the shooting, while Taser's shares had risen nearly 27 percent.

The Ferguson police got to test-drive a new device over the weekend: body cameras, which officials hope will show a clearer picture of what happens during police incidents like the ones that occurred during the Ferguson protests. About 50 cameras, which are positioned on officers' uniforms to enable up-close audio and video recording, were given to local law enforcement by two manufacturers and tried out on Saturday during the most recent Ferguson march, reports the St. Louis Post-Dispatch. "[Officers] are really enjoying them [and] trying to get used to using them," says Tom Jackson, Ferguson's chief of police. The subject of body surveillance equipment for cops has become a hot topic since the shooting death of Michael Brown. Although some critics claim the cameras might be an invasion of privacy, law enforcement agencies and the ACLU are all for them, reports Reuters. Another St. Louis-area police department has already approved buying the devices for its force, notes the Post-Dispatch, and NYPD Commissioner Bill Bratton said at a news conference last week that his department is "actively looking" to use the technology, reports PoliceOne. It looks like other departments may be following suit: Digital Ally, one of the companies that supplied the Ferguson police with its cameras, says it has witnessed a "fivefold" jump in camera inquiries since Brown's death, notes Reuters.
