You’ve probably already been told this, but in case you missed it: one of the elements, the biggie, for first degree murder is intent. This case doesn’t seem to show any intent. Manslaughter seems more likely. You can google “elements of -whatever crime you want- and put the pieces together yourself.
I submit that if his sidearm was already unholstered, there was “intent” to use it. That he fired inside the car, across the front seat where the driver sat and had but one target, the woman talking with his partner, there was a certain level of “intent”. These things just don’t “happen”. This was no accident. This was a premeditated act. He had to unholster, take “aim” and fire the weapon at point blank range into a civilian who had called the department for an unrelated issue. The LEO’s and sycophants making excuses are disgusting.
