Perhaps I'll just go back to the excited delirium. My recollection, going way back, is that we had incidents of people handcuffed and dying in police cars. At the time, we weren't sure why, but I think, after the fact, medical people started to talk about this phenomenon called “excited delirium”. They weren't necessarily people who'd had any particular force used on them.
I wonder if either of you could comment, if you're aware or if you could confirm that in fact that has been the case in the past.
