Except it points out how many were shot in head. Targeted for kill rather than just wound

The head shots suggest the weapon was a rifle as well IMO. Not likely you get 5 of 9 killed with a head shot using a pistol. Possible certainly, but not likely. More likely to aim at center body mass with a pistol.

Sniper?
If targets were not life threatening then its a clear case of over reacting
