Rather than respond substantively to the people who called him out for being dead wrong, he instead trashed people's grammar. I mean, isn't that basically an admission that his only way of responding to otherwise valid points was to personally attack a few poorly worded tweets? He didn't post a real reply to anyone...just made fun of people. The guy is a douchebag.
Also, I'm a lawyer, and he has been a complete train wreck in terms of his legal analysis about the Penn State situation. It seems more like he's a guy who watched a few episodes of Law & Order rather than a licensed attorney. I mean, he actually used the phrase, "Paterno has turned state's witness." LOL. You really should only say something like that if 1) you're in a movie, 2) you're talking about someone in the mafia, and 3) the mafia person was accused of a crime. You can't "turn state's evidence" if you're just providing testimony, like Paterno will likely do. Clay=Dumbass.
