This was a felony stop. Gutierrez states that to the dispatcher as he exits the vehicle
A temporary vehicle license out of place is not a felony. It's not a misdemeanor either. It's actually a minor civil infraction that usually results in a warning.
Once it became apparent that this was the only thing amiss and the vehicle was not stolen, which was very early on, the justification for the felony stop came to an end and it was time for the officers to change tactics. The Windsor Chief of Police has acknowledged as much himself.
To quibble over whether Nazario was too slow to comply with an unjustified level of force misses the point that the level of force was unjustified.
Brandon Tatum, who is the author of the 33 minute YouTube video at the start of this thread is either misinformed or lying on a number of fronts. He claims it was a traffic stop. It most certainly was not as Gutierrez clearly stated. As a former Tucson police officer, Tatum would have been familiar with the procedure for stopping safely in Arizona, which I've posted on this thread. His righteous indignation that Nazario proceeded for almost another mile in a state with a virtually identical procedure is therefore either disingenuous or ignorant.. His claim that Nazario didn't even slow down is demonstrably false as it's contradicted by the transcript of Crocker's radio communications. The guy's videos are frankly garbage. I've no interest in watching any more of them and am surprised that you do.
It the spirit of your thread though, I agree that it's very easy to criticize and much, much harder to do quality police work. Anyone who can do it and maintain their composure is a much, much better person than I am.
