APD is trying to justify their murder of Mike Ramos because they're arguing him driving a vehicle (AWAY from officers) was him wielding a deadly weapon. this guy drove a car directly INTO protesters; if a car driving away is a deadly weapon, a car driving into a crowd would be doubly so. even if they're not absolved in the Ramos case, they've shown that they believe/agree that a vehicle is a deadly weapon.You can't if you initiated the confrontation/violent action/whatever.
It's why they'll be looking at the behavior of both the car and the rifle guy. Measuring video frames to determine acceleration, reaction time, etc. One of those deals that can come down to little seconds long snippets in time as to who a reasonable person would perceive as a grave threat and when, why, etc.
Driver may well be at fault. Or not. Or a toss up somewhere in between for lawyers to argue over.
Some camera or combination of cameras somewhere down there will have caught it.
