TB is a nasty infection. It is however not exceptionally easy to catch. I've been exposed to it many times, and have yet to become infected. (It's a job hazard). I would think at the least, he should have been wearing a face-mask, which has been shown to dramatically reduce the transmission of the illness.
I heard the guy is a Lawyer (read: Bottom feeding scum sucker), which probably is why he's wrangling with the "absolutly don't fly" recommendation from the CDC.
