For those so inclined, here's a lazy-person's way of suggesting to the "Big Three" networks that maybe, just maybe, there might be more of import to report -- or to lead the newsbroadcast with (heavy sigh) -- than prurient coverage of a guy who probably had nothing to do with a ten-year-old murder. Is signing a petition the most effective way of making your voice heard? Nope. But that's not to suggest that such things do not matter, or that they cannot have influence.
On the topic of things that might matter more, again for those so inlined, there's a rally Sunday, September 17, 2:00 PM, in New York's Central Park, to (yet again) try to draw attention to the continuing genocide in Darfur. Numbers matter, and such things can, in truth, have influence, not least because the more people there are there, the more media coverage the event is likely to receive, and the more likely government(s) might feel pressured (out of electoral self-interest, if nothing else) to act.
And a fall afternoon in the park is a rather painless way of communicating to your government, and communing with your fellow citizens. Pack a lunch. Make a day of it.
