I fly a LOT, on various airlines, and have never seen such brutish results stemming from an airline's OWN failures.  UNITED either didn't know or didn't plan for the fact that its OWN employees would "need to fly" on (supposedly) only THAT one UNITED flight. And, apparently, UNITED's own employee-in-charge-of-boarding failed to properly incentivize volunteers-who-could've-taken-a-later-flight BEFORE he let ticketed travelers BOARD the plane.  

Also, if this article Is updated, it should correct its apparent error in initially mis-applying the term "police officer" to the outrageous guy who roughed up the distraught passenger.

Only the article's 2nd-to-last sentence (the local Aviation Dept's little p.r./c.y.a. statement) uses the correct job title of the out-of-control "security officer" who's now "on leave" (until, I expect, he takes a quick online 'class' on tactics & self-control just for Low-Bid 'Security' Contractors -- OR until the public's fleeting outrage is forgotten).
