He was at home when it happened. There is no proof he was drunk as no alcohol was found in his system (which they usually test for). It's more likely than not that he wasn't drunk or it would have been proven through someone saying he was or tests. He doesn't remember because of the severity of the injury which is unerstandable. The commonly reported part was that he was sleep walking or that since it was so dark he couldn't see and tripped.
There seems like no reason he would need to go down the steps anyways.
There we have if it, zero proof he was drunk yet some clowns say he was like Its fact, that pisses me off a hell of a lot
I'm not certain he was even tested for alcohol when he fell. As it did not involve driving nor any other person, he very well might not have been. As for "assuming" he was drinking when he fell, well, when you make poor decisions (and they seem to involve alcohol) that does happen.
Whether or not the fall was the result of alcohol or not, he has had more than one incident.
"Kindle, the Ravens' first draft pick in 2010, fell down a stairwell at a friend's house three days before training camp opened and suffered a skull fracture that has sidelined him for the year and jeopardized his career. He had been arrested in a drunken-driving case while in college in 2007 and crashed his car into a building in 2009, an accident he blamed on driving while sending text messages. Kindle is on the nonfootball injury list and can take part in physical therapy with the Ravens but cannot participate in football activities."
He was arrested for drunk driving after falling down those stairs where he tested for twice the legal limit.
