There's a fine line between judging too quick vs acting too lenient.
No one in this thread is arguing for leniency. The different posts in this thread seem to be indicating that McDonald's punishment, if the charges are legitimate, should be severe.
Tell me how society/authorities should react if child pr0n allegations are thrown against an elementary school teacher? Abuse of power charges against law enforcement? Should we just wait until there's undeniable proof/evidence. Sometimes the idiom 'better safe than sorry' should prevail.
I would hope his girlfriend isn't putting herself and her unborn child in further danger by staying with him. But beyond that, I'm not sure how this thinking applies. It would make more sense if he assaulted a teammate or a coach.
For as many Duke lacrosse players, there are UC at Berkley female students who got swept under the rug because of their (ultimately proven) allegations. But, we digress and are approaching P/R level discussion.
I've stated my stance on this MacDonald situation, and I'm taking it to the extreme with the above situations. Just saying it's not always as black and white as "innocent until proven guilty".
Here's the sports-specific issue: These players are public figures to at least some degree. Look at how badly allegations of rape damaged Kobe Bryant or Ben Roethlisberger's reputations. Look at how badly the NFL's PR was damaged by the Ray Rice wrist slap. Has Goodell apologized for anything else ever? Chris Andersen (better known as Birdman) almost fell out of the NBA because of being charged for committing crimes against children that he didn't do.
No one's saying it should be black or white (at least I don't think so). Even if criminal charges aren't filed against McDonald, the NFL should suspend him if its own investigation finds evidence of wrong doing. But, while we shouldn't prioritize these guys careers over the damage they've done to their victims, it seems reasonable to make sure that damage actually happened.
