If you are reading this in Denver, CO, there's an emergency protest outside the Denver Post. Email said starts at 11, didn't give an ending time.
If you are somewhere else, look around. Bet there's one in your area. Or maybe you need to start one?
To me, this was a murderous attack on people who were only bringing humanitarian supplies to desperate people. I happen to admire people willing to do that. And I'm horrified at their murder. Are we going to let this pass in silence?
If there are no Israeli government institutions in your area, targeting the local corporate media is a good idea. Be willing to bet that your local paper is reporting this like the Denver Post ... ie ...long statements direct from Israeli officials giving their justifications ... then maybe down near the end of the piece you might find a paragraph that says 'activists disagree'. In other words, they are directly pushing out the Israeli version of these events.
Which makes them accessories after the fact to the murder of humanitarians, and certainly worthy of a crowd of people with signs outside protesting their involvement.
