With Obama's Support, Police Body Cameras Could Become the New Normal

For people who support putting cameras on cops, this is a very big deal. The White House plan is intended to outfit 50,000 officers with cameras, which would almost double the number of cameras in use in the country. There are currently two major U.S. companies selling body cameras: Vievu, which has sold more than 40,000 cameras to 3,900 police agencies, and Taser (TASR), with 30,000 cameras in use by 1,200 agencies. The $75 million earmarked to purchase new body cameras is more than seven times the total revenue Taser earned from selling the devices in 2013.
I'm curious what impact this will have on citiziens (especially of certain backgrounds), law enforcement officers and the society in general. We are now talking about considerable numbers.
