Although we miss the beginning of that incident (how convenient), after the video starts I see no indication of what would be disorderly in Texas. It does appear to be a case of officiousness on the part of the LEO.
But I wonder, SR9TX, what is your point? Do you have an opinion on this?
It would appear the deputy lost sight of common sense resolution options. As a LEO, the focus should be on the end result of peoples' actions - including his own. The outcome here did not serve any positive purpose, for anyone.
