Most of these men (and women) are pretty faces that graduated from college with a degree in communications. They're used to covering bar mitzvahs and community picnics. So when they come to demonstrations, they're not in their element. They generally operate under the (misguided) assumption that the cops are there to protect them. I've seen them, time and time again, cowering next to police lines, making small talk with cops and looking fearfull if their more than 15 feet away from a cop.
However, from time to time, they get a little dose of reality. This normally looks something like what happened to the channel 12 guy. He accidentally got in the way of an act of police brutality and was brutally beaten and arrested himself. The fact is that, no matter how privileged you are, if you interfere in the business of the system, you will be treated without regard to that privilege (just look at all the brave men and women who took pepper spray and clubs despite their middle class status).
Of course, as the Channel 12 example shows, the higher ups quickly regain control and revert to business as usual. But this should give us some food for thought. There's no reason to be nice to the corporate media (they're complete tools after all). But on the other hand, we don't need to be confrontational either. We should still block shots that might (for whatever reason) might make us look bad. However, we should try to alienate them less than the cops are. Remember, these people are human. From time to time, they act like it.
Disclaimer: these are just my thoughts. I didn't actually see the Chanel 12 incident. If people can explain why this strategy is bad, I'd like to hear it. The fact is, I don't really know how to act around the corporate media myself. The discussion a few days ago was great, but I feel this latest incident was particularly instructive.
