The concept of bullying gets a lot of attention these days. We have bully free zones in schools, for example, but maybe we need to extend that to governmental offices. Reference the following:
New York Congressman Michael Grimm threatens to "break reporter in half"
The good Congressman reminds me of Biff from Back to the Future.
This one is pretty short and sweet, at least as far as I see it: Congressman Michael Grimm is a disgrace to his party (whatever party that is, as it really doesn't matter), to the people he serves and to the United States Congress. He should resign, like yesterday. Think about it: this guy is making threats to someone he doesn't know; what does he say to people he does know that upset him?
I know, I know, the "mean reporter"...blah, blah, blah. Want to be a public servant? Then get used to getting asked question on the spot by reporters. It's a job requirement. It comes with the territory. Grow "a pair" or step aside for folks who wear big-people pants.
Oh, and I'm not saying this from the standpoint of "think of the children..."; trust me, no children are interested in the antics of Congressman Grimm, or any other member of Congress for that matter. This isn't about "the children", it's about a Congressman who is incapable of managing his emotions in a way that is even remotely acceptable this side of civilized society.
Resign Congressman Grimm, resign. Your apology isn't enough (but do check out the cartoon in the link).
