I'll agree that all 4 of your non-provocative behaviors should not escalate a situation to the level of deadly force being required. I specifically asked for examples from the list, because the list seems designed to support a very specific thesis, one that you expressed in this comment:

    > It happens far too frequently that Americans are killed 
    > by police firearms when they are not posing an immediate 
    > and credible mortal threat.

"far too frequently" is a fuzzy number, one that's hard to agree on. How many unjustifiable deaths per year is that? I believe the data in this article is intended to be used as a stand-in for that figure, and I posit that the actual number is dramatically lower than the fuzzy number everyone has in their heads.

If you want to really shut up the naysayers, try showing this data:

    Interactions between civilians and LEOs:  __________
    Of those, how many involved physical force? __________
    Of those, how many resulted in fatalities? __________
    Of those, how many were unjustifiable? __________
    Of those, how many went unpunished? __________

If that last number is more than a handful a year in the US, I'd be shocked, outraged, and offended. And certainly we should be shocked, outraged and offended for each individual incident of that last kind no matter how many others there are.

That being said, if you want to claim that we need "a civil, national conversation" about this, I think the onus should be on you to prove that the last number above has risen to a national crisis level. Maybe it has, but I don't think this article (or even your 4 examples) makes a very good case for it.
