I very sure the cop did not wake up that morning and day to himself, “I’m gonna kill Philando.”
The problem for both the officer and dispatcher is going to be the discussion about the “Wide Nose.” That won’t get the cop or dispatcher convicted, but will doom the city in the civil suit.
Another problem is that while the officer thought Philando was an armed robber, he did not request, nor did the dispatcher request additional back-up. That also will doom the city in the civil suit.
There was backup at some point, lots.
It can be seen in Reynolds video as she pans the camera, tons and tons of cops.
What we don't know yet is the time between the stop and everything that happened worth knowing.
