I'm guessing that students are doing projects or presentations on Emmitt Till, because the majority of my hits today seem to be from web searches for Emmitt. No wonder. I'm #4 on the google search.

I guess I'll be nice and help them out with some places to start:

Here are those pictures you've been looking for. Man's inhumanity toward his common man.
Here's a story about a modern-day lynching in Mississippi.
Here's a song.
Here's the website of the recent PBS series on this subject. I found viewing this series heartwrenching.

Hope I could help.
