Taser International, the corporation that manufactures and sells electroshock weapons to police, is experiencing a market gain in the wake of Ferguson and the killing of Michael Brown.

Its stock rose three percent on Monday and has gained 44 percent since August 1.

Digital Ally, a company that makes miniature cameras worn by police, has seen a 228 percent increase in the same period, according to Benzinga. Its stock shot up 57 percent Monday. The company recently issued a press release noting it has seen a surge in sales since the trouble in Ferguson.

Taser also manufactures digital cameras for law enforcement. Its video product represents 36 percent of the company’s recent second quarter revenue of $3.4 million.

Taser cites a two-year study by the Rialto, California police department in collaboration with a researcher from Cambridge University to claim its wearable cameras result in 60 percent less violent encounters between police and citizens.

In recent days thousands of people have gathered in New York, Pennsylvania, California and elsewhere around the country demanding government intervene to put an end to police violence.

Political pressure on police to address violence and militarization prompted the former New York Police Commissioner to call for a review of federal programs arming police departments with military-grade hardware.

“I think the military equipment, the distribution of excess military equipment, has to be examined,” Ray Kelly told ABC News. “People get uneasy when they see Humvees, military vehicles, heavy weapons.”

Pentagon Defends Militarization Program

The Pentagon has defended its 1033 program providing military surplus to cops despite criticism from congressmen, including Senate Armed Services Committee chairman Carl Levin, a Michigan Democrat, and Rep. Hank Johnson, a Democrat from Georgia.

“These guys are idiots – riding around on the top of armored trucks looking like rednecks on a country drive, pointing their weapons at unarmed Americans,” an unnamed Pentagon official told The Christian Science Monitor last week. “Don’t tell me that’s militarization – our troops would never do that stuff, even in a war zone,” he added. “And why are they riding around in woodlands camo in a city? That kills me.”

Militarized police in Ferguson, Missouri prompted Obama to call for a review of 1033. The review will more than likely not call for an elimination of the program or a significant demilitarization of police.

“Among other things, the president has asked for a review of whether these programs are appropriate,” an anonymous senior administration official told The New York Times on Saturday.

The review will also reportedly determine “whether state and local law enforcement are provided with the necessary training and guidance; and whether the federal government is sufficiently auditing the use of equipment obtained through federal programs and funding.”
