Well, it is very funny.
Well, I don't share the OP's view (or is it some misguided hope?) that this might change CSI, I also have to take issue with the first responder's assertion that the Webisode "isn't factual at all" about biohazard removal.
Sure it kind of skips over the part of the process where they'd bring in a pressure washer to give the final treatment to the grout and stone work, but the part where Dan (Dale Midkiff?) talks about how blood coagulates into a jello-like substance and then you just shovel it up was like one of those Chuck Palahniuk factoids -- the ones that seem counterintuitive but are also darkly funny and true.
I looked it up and the Webshow is exactly right. That's how they do it -- pretty funny.
The part about how you have to use a putty knife to remove brain matter because it turns into concrete is also really funny -- in that totally twisted and dark way. And it's also exactly right.
So I don't know about it not having it's facts right.
CSI certainly glosses over it's fair share of stuff and plays loose and fast with the rules and this show kind of calls them on it, while being funny on its own.
I can also see people who really work in Crime Scene Clean Up being really wry and detached and kind of misfits like those guys -- must be a pretty macabre type of work so they probably cope with humor just like all of us.
All in all I thought the video was pretty hilarious and I think Brockman is overreacting by saying it doesn't accurately portray Biohazard Removal.
