Entertaining, sure. But helpful? No.
Anybody can pick up a camera and provoke someone into reacting and then use that as 'evidence' of some perceived slight. Yea, it makes for a great 'look at this from the left' or 'look at this from the right' shit -but it is no more legitimate than a 'he said, she said'. Personally, I think it is doing the country a lot of damage. We seem incapable of seeing beyond our own stupidity. Except me, I can see it.
It seems to me that the only time any of hte politicans are asked legit questions is by people like Mattera. So, youtube has become the only way we, the people, can see how well these nit wit politicians react to legislation that they don't even read let alone care to explain. Franken is jerk.
