If you'll watch the full 9 minute video and read the article, you'll find out that guy turned out to be a stand-up guy when talking to the ranking officer on-scene, saying the cop did everything right. At first viewing and if you cut it off too soon, I'd agree that a back-up officer would have had him cuffed & stuffed.
At the time the cop was trying to approach the punk the officer did not, and could not know he was a stand up guy. The only thing that mattered right then is that he was not following the officers instructions and caused the officer to stop to deal with him. I'm glad this guy turned out to be a great American but even great Americans can cause problems for LEO's when, in a stressful situation, they do not do as the officer instructs them.
