Yes, absolutely, the real problems that need to be addressed here are U.S. police training and institutions. Ending the War on Drugs would be a very good first step, then we need to actively re-structure the existing institutions and training to be more focused on de-escalation, conflict resolution, and community outreach. This would however be incredibly expensive, time-consuming, and in the case of ending the War on Drugs extremely unpopular for several reasons.
smjjames: You're pretty much right on the money there, tho' it is important to note that the NG were called in for what amounts to riot duty, and the Ferguson police were the target of those protests, leading to greater friction that went away when soldiers were on the field instead of the police. We can and have used military assets (tho' it is important to understand that the NG and Reserves aren't exactly the same as the Army proper) to help deal with high-tension situations, and that is part of their purpose, but they just aren't viable for long-term application to this problem.
Nenjin: Yes, the M.P.s are the ones carrying out those duties. You are factually incorrect on this point. They are not the ones gathering data on insurgents however, that duty falls to intelligence personnel. The Army (and other branches of the military) are divided into different M.O.S. specifically so there are personnel with varied skillsets within the organization, those people are deployed where their skills are needed.
