Definitely a sad, sad story to read about BJ. Truly one of the kindest and most humble of the top U.S. runners of his time.
We all have flaws, we all make mistakes. For most of us those flaws and mistakes are not made widely known or publicized, as is the case in this instance.
While no excuse for what BJ allegedly did, we ought to remember each of us is far from perfect before casting the stone and judging.
We don't know if BJ is addicted or if this was an anomaly. Regardless, lets be in his corner to support him - and perhaps more importantly - lets be in the corner of the people in our lives where we have contact and can help.
Support does not mean the actions are condoned, but that we help that individual in whatever way we can to move past the challenge, learn, and not repeat (and make restitution as necessary).
