Yes, they are victims of an over-crowded course, because we are all victims. No one is ever responsible for what they do, someone else is always to blame. :)

Your smiley face is duly noted. I'm all for accountability. However, I do feel sorry for the slower swimmer/faster cyclist who might have happened upon one of the filmed groups and might have been trying desperately to get through or past the group. I think it's fair to ask if there aren't more blocking violations in evidence on those videos than there are drafting violations. I've yet to attend a race where I didn't see WAY more blocking than drafting (though I've never attended an IM-branded event). You're supposed to make your pass and then get the f__k out of the way!
