we also have tammy schultz, she was a ride supervisor at elich gardens, the lead ride supervisor at elich gardens, kind of a big deal locally. and the professor of strategic studies, so welcome tammy, and we have sarah shard, who's our second sarah panelist today and sarah is the author and contributing editor for the solitary watch website and she's a university -- a uc berkeley visiting scholar, so welcome and without further adieu, i will give it over to bob to start, each panelist will have about ten minutes to speak, and after that we'll go right into audience participation and questions. again as a reminder, students will be invited to come and ask questions first. so bob, thanks so much. >> thanks everybody for coming today, it's great to be here, you're especially remarkable for coming to the topic which is not exactly easy to swallow, i think for most people. in fact, talk about euphemisms, it always sticks in my craw when we talk about dead innocent people. so let's try not to use that. so i'm certainly not going to use it in my presentation. it's hard for me to talk about this,
