I was coming home on the SW Chief (Amtrak) today. Around 10:00 AM a Laguna man (Indian/Native American tribe) either pushed or chased another onto the tracks in front of the speeding train. We were stopped for four hours while tribal officials, FBI, NTSB, etc. investigated. The body was strewn all over. Someone in the seat nearby said something about taking a picture. I told them not to, that for one thing the cops were right outside and could see them, and for another it would be a very untasteful thing to do. The man got mad at me. Should I have kept my mouth shut? I am all for photographers' rights but for one thing it was tribal land we were on. It was also one of their own that was killed. Out of respect I didn't think it was proper at all. He never took any pictures in the end but made more sarcastic comments to me. He was from Tennessee and probably doesn't know much about the various customs of this part of the country.
