It's important that more people see officers and get the impression that they are there to enforce peace, not dole out violence -- while still ensuring they have the tools to maintain safety and order. Large, threatening military-style vehicles don't send a good message to people who are already scared for their safety.
I don't remember who said it, in relation to sports - "Look good, feel good, play good." I think how you look can absolutely affect how you behave.
People trained by the military to police occupied communities should not be allowed to act as civilian police in peacetime conditions.
The rule of engagement in places like Iraq and Afghanistan are significantly stricter than they are for America's cops. No firing until fired upon, limits on use of things like tear gas and riot gear, etc. They're also trained significantly more.

> In contrast, soldiers continuously and over the course of their careers repeatedly train to employ techniques to deescalate stressful, unpredictable, and dangerous scenarios. They also know what steps they must take before resorting to lethal force. Most rules of engagement (ROEs) — the military’s term for rules that govern the circumstances when soldiers are justified using force — contain explicit instructions requiring soldiers to use verbal warnings, show their weapons, and exhaust all non-lethal physical options before resorting to deadly force.
