This is just like the argument some make for the need of "stop and frisk" in areas of NYC. They state that stop and frisk is an effective tool to combat illegal guns and drugs and the reason it is being "proportionately" employed against minorities is because that is the population demographics of the areas where the highest instances of violent crimes occur.To find answers we should look at the crime statics in the city/area where this "militarization" is taking place. That way we can compare equipment to need.
