Put this frigging cop in jail...now.
# 38) "Criminal Cops shooting criminal suspects. Criminal suspects shooting criminal cops"
Difference is, innocent cops are being killed by criminals. Why would you assume that the cops being killed, randomly, are bad people. It is highly probably that they are/were decent folks.
This type of killing simply needs to be prosecuted, and justice needs to be delivered. Unless some other video, from some new angle shows the suspect pulling out a light saber...I don't see how this cops(s) gets away with it.
However, it doesn't lend itself to a "payback" where some random cop gets killed in retaliation. Only a deluded mind (you potentially?) would make that kind of leap.
