Rules of Engagement

I've been gathering helpful hints from news accounts so here are the rules of engagement according to the media:
Never shoot anyone over 60.
Never shoot anyone under 18.
Never shoot anyone who has a disability.
Never shoot anyone on their birthday or the night before their wedding.
Never shoot anyone who likes children, was going to make something of themselves, or had an interesting hobby.
Never shoot anyone of a different race, gender, or culture than you.
Never shoot anyone unless they have a bigger, closer, and more visible weapon than you.
Always try to figure out why somebody wants to kill you; it's obviously something you said or did that provokes them.
Always give the person at least one chance to shoot or beat you first.
Tasers are evil but you may use them if the person has a gun.
Since you have unlimited back-up immediately at all times, two big strong police officers can always easily subdue another person due to your special training and other superpowers without harming them.
How hard can it be?
