I have 7 yrs patrol experience and I go in today at 3P. I agree with Bailey that it is hard to arm chair another officer based upon the video presented.
You don't see the driving behavior prior to the activation of emergency lights. I would want to know exactly how fast they were traveling. I would want to know why the driver didn't pull over when the officer tried to initially stop him. I have been in this situation before where you can't get off the road all the way due to snow pack on the shoulder. I have always stopped the car and then asked them to pull over at the next exit if I felt we were in danger from other traffic. I agree with Bailey, I'm not sure that was a PIT, If it was i don;t think she had enough room for it, however the speed would be ideal.
I don't think I could give anyone a call on this one without more facts. I have seen good calls and bad calls in my career bot in person and in training.
I do agree with taking him into arrest at gun oint due to his aggressive response when exiting the van though. That's what i would have done, and have. On most stops you have no idea who's in the car old man driving home, gang banger, teenage kid, man wanted for homicide, or a guy driving his kids home from a New Years party. again just my .02 cnets
