Essays / Getting ready for an inclass essay about the militarization of police. [2]

In a couple of days i have to write an inclass essay about how militarized the police has become, and take a side on whether I think they have become to powerfully equiped or that they are deserving of this equipment. I personally think that recent actions from the police themselves show that they are not responsible enough to have this kind of equipment

I cannot pre-write the essay, only outlines are allowed. So i would appreciate any help that would help me get started in developing a main idea, argument or topics i could address in the paper.
