What if he had just pushed her grouchily and not violently, and she tripped and hit the cage face-first? I'd like to see if the police report really uses the phrase "slammed her head into a metal trash can cage."
My point isn't that it's okay to beat women, far from it. My point is that the author of this article seems to be using some pretty strong words to describe the incident (which could be an indicator of an agenda), and those same words may or may not have been used in court.
Here's why I'm VERY hesitant to judge either way when I read something from a single source: When my niece was about five or six, I was in a friend's garage playing ping-pong when she started to walk in the door. At the same time, I was reaching for the ball which had rolled over next to the door, and when I stepped back my (rather hefty) butt hit the door (which was by then a little less than half way open) and the doorknob was knocked into my niece's forehead. Popped her pretty good, and left a pretty gnarly looking bruise. When talking to her uncle (my sister-in-law's brother), he asked her what happened, and she told him "Uncle Dave hit me with the doorknob." Dude was fixin' to come at me like a spider monkey, thinking I was beating up a little girl. If my sister-in-law hadn't actually seen it happen and stepped in to convince him that what I said happen was really true, it probably would have come to blows.
Knee-Jerk reactions aren't always the right reactions.
In the case of the Congressman's son, I can see how the injury could be much worse than the severity of the attack, but since he's in Congress, he won't get the benefit of the doubt from me. I smell misuse of influence...
