Dear Two,
That is one version. Possible. There is a reverse version. Also possible. Is the truth somewhere in the middle? Possible. Really weird situation. To me, this has a lot of echoes of Ferguson. The story brings up broader questions about the whole city.
The only criteria needed for resisting arrest, is that the officers had to attempt one. This was not immediately confirmed. And at this point, is conflicted. There will end up being to completely different versions. What is unique here, is that there is a survivor, multiple witnesses, and video evidence. We should get some truth eventually.
This all does not address why he was shot after the fact. If we are having a contest as to win can make the boss into heroes, I won that one long ago.
