Earlier that day, the president rolled out a list of military equipment that will no longer be available to local law enforcement, including tracked armored vehicles (tanks, basically), weaponized vehicles, large ammunition and firearms (.50-caliber or higher), grenade launchers (why were these needed in the first place?), bayonets, and some forms of camouflage uniforms.
The public is split on the topic of state and local police using equipment designed for the military. In an August 2014 USA Today/Pew Research poll, people were asked to weigh in on whether they felt confident that local police could be trusted to use military equipment appropriately. 45% of those polled stated that they either had "not too much" confidence in police or "none at all."

The initiative will make certain data available and more accessible to the public and will also help police departments internally identify officers with troublesome behavior patterns earlier:
"While many police departments have systems in place, often called “early warning systems," to identify officers who may be having challenges in their interactions with the public and link them with training and other assistance, there has been little to no research to determine which indicators are most closely linked to bad outcomes. To tackle this issue, twelve police departments committed to sharing data on police/citizen encounters with data scientists for in-depth data analysis, strengthening the ability of police to intervene early and effectively." — Launching the Police Data Initiative
In Oakland, where police have been wearing body cameras for the past four years, a team of data scientists from Stanford University is going to "comb through the audio to surface police/citizen encounters that either went particularly poorly or went particularly well." From this data, the Oakland Police Department will be able to "quickly identify problems and also to lift up real world examples of the great police work that happens every day."
It might be a few years before we start to see the effects of this data collection, but this is definitely a step in the right direction. You can watch Obama's full speech in Camden here:
