No, tinco is right about officer safety. You really want those "men with gun and right to use deadly force" to feel safe, so that they don't exercise their killing license prematurely. When the officers feel safe and thus sure of themselves, they're more likely to follow proper procedures instead of being afraid of their own safety.
I'm not saying that you should give them armoured troop carriers though. You want them to feel safe, not invincible.
