I believe that video was sped up, it DOES show the officer leaning into the vehicle to cause the bump.It was more than a simple bump. Start at about 3:45 for a full speed video of the impact. You might also be interested about the relevant Minnesota law about the use of force by LEO in Minnesota.
Look at the speed from the first video that guy showed, compared to the second one.
That second video LITERALLY shows the officer trying to be struck.
