As the debate over the use of law enforcement body cameras rages on, one thing is for certain: Business wins. The tragic use of police force in recent years has increased the call for body cameras. Innocent victims could receive justice, some say. Others feel that cameras would exonerate more police officers. What's for certain, though, is that law enforcement tech companies will reap the greatest benefits. Interest in Taser stock has soared in recent months. Why? Taser makes the popular Avon line of police body cameras. These tech devices are already in use across the nation. And, as the public demands accountability, the sales keep rolling in for Taser. Experts believe that body cameras and related technologies have unlimited growth potential. Taser does face competition from a giant in the field of technology, Panasonic. Moreover, smaller companies like VIEVU, Digital Ally, and Wolfcom are all interested in "joining the party." With more than one million law enforcement officers in the United States alone, the profits to be made are significant, to put it mildly. In the end, history demonstrates that controversial police actions will continue to make headlines. As well, public outcry will rise and fall as situations demand. Just as certain is the fact that debate over the use of body cameras—becoming what's essentially free advertising in the public sphere—will continue to expand their use. The most consistent "winners" in this expansion won't be justice or even truth but tech companies and their shareholders.
