watch the replay carefully, Kimo V O has his head up as he's hitting Palmer so it's not like he didn't know where he was or what would happen if he took his 300lb body into Palmer's knee. maybe it's not the same thing as a premeditated because it happened in a flash but there's is no doubt that KVO intentionally continued forward and reached for the leg despite surely knowing what happens when you hit a guy that low that hard.
Disgusting cheap shot, period. And the ref stood five feet away and didn't even flag him for hitting a QB in the knees. Sean Taylor is a jerk for his actions, but spitting on guy gets you kicked out while intentionally crushing an unprotected QB in the knee gets you nothing? Pittman wiped himself off with a towel and was fine while Palmer's very career is now in doubt.
KVO absolutely better get a suspension and a fine for this one....
