@Dave Newman Re: He made one mistake
I suggest you actually listen to the tape of the incident.
Ben Jacobs did ambush him and didn't take no for an answer.
As to having the right to take down Ben, it depends. We don't have video so we don't know how close Ben was to the politician. Was he invading his space? While the politician has been charged with misdemeanor assault, there are some charges that could be lobbied at Jacobs as well.
IMHO, its time so called journalists understand that when you attempt to ambush someone and try to goad them in to giving you an off the cuff response that you can then attack... you may get a fist in your face.
