The second one is funny because it made everyone in the office realize that living conditions in a posh prison were way better than their life in Dunder-Mifflin. The guy was pretty nice, but Michael had to do it all about his race and eventually made everything so uncomfortable that the guy quit because of the hostile work conditions. They only realized he was exconvict because the government gave them a financial incentive for hiring him.

The first one is harsh because the dude was very obviously mentally challenged. He needed a good family environment and mental health care, not two FBI thugs harassing him.
