On the other hand, if an officer has a weapon holstered and a suspect appears to be reaching for a weapon, then it is far more justified for the officer to draw and fire, as there would be far too much risk upon the officers life if he waited for actual presentation of a firearm.
Once a gun is already pointed at another by a trained individual (either LEO pointing at suspect or suspect pointing at LEO) as long as they are more than four feet apart, there's pretty much zero tactical chance of the other suddenly pulling a weapon from concealment and successfully getting it up to (successfully) shoot before having at least a couple holes punched inside them.
TLDR: If officers (especially multiple officers) already have guns drawn and ready, then it needs to be a "only if you see a weapon, or they try to otherwise physically attack, then you can use deadly physical force".
If officers have not already drawn their weapon, then it needs to be a "if they appear to be going for a weapon, you can use deadly physical force" policy.
I'll ETA: There are 14 "civilian" career professions that are more deadly than career law enforcement, the 15th deadliest profession. Even things like roofers are 4x more deadly, pilots 5x more deadly, even your taxi driver and groundskeeper have a statistically far riskier career. There are certainly risks involved, but I do tire over the myth/perception that it's an incredibly dangerous job such as that "normal" people cannot comprehend the risks.
ETA 2:
6,937 military casualties in operation Iraqi freedom and afganistan since 2001; not counting any other combat and non-combat fatalities at home and abroad. I'm not sure how to get those figures, but it would definately add several hundred if not a couple thousand.
2,687 total LEO casualties in that same period.
If we do a broad scope, total LEO casualties since our founding: Approximately 20,000
Total Military casualties since our founding: Over 1,300,000
LEO fatalities are tragic; I just don't want to diminish that of the soldier...
