Why?
We don't have shootouts with drug lords going on. My city has suffered exactly 3 officer deaths on duty in the last 25 years and only one of those was by gunfire (15 years ago). I utterly reject the reasoning that my city's officers need to be made to feel safe by the acquisition of ex-military hardware.
Let me be as clear as i can, that vehicle does not make me, the citizen, feel safe. I've seen them deploy that vehicle for something as common has a home robbery. This is not Afghanistan, criminals are not enemy combatants. When you have that kind of hardware sitting around, you will find a use for it.
I don't know what kinds of 'nice things' you are referring to, i'd love to hear examples. Lastly i reject that euphemistic description of that troop carrier as a 'robust all terrain vehicle'. This is a well paved, suburban, low violence city; not Kabul.
