So far, only one thing that I remember significantly differently, and that is that I don't think the pipes were long enough to leave space between people's outstretched hands. My impression was that the demonstrators were holding hands _inside_ the pipes, and that there was only space if they dropped the hold.

One difference that age has made for me is that I found myself identifying strongly with the firemen (firepeople? I couldn't see their faces) cutting through the pipes; I _know_ how much they didn't want to cut off anyone's fingers. When I was 22, I think I would have figured that they didn't want to get sued, but I now know that the fear of injury was a big personal cost to (many of) them, as well as to the demonstrators.

Personally, I can't imagine letting someone run a circular saw that close to my arm when I could just take my arm out of the pipe and save the risk--but I'm impressed with the conviction of the protesters and the care of the firepeople, glad I was there to witness, and glad that no one lost any fingers (or any blood) in the process.

What I recall is that the chained demonstrators were either gripping or shackled to chains that ran through the tubes. I very definitely observed that after a section of tube was completely cut throught and pulled aside, there was chain in the middle that also needed to be cut.
