Mitchell robs a restaurant, carjacks a car for his getaway, and leads police on a chase before being captured (and fires a random shot at them while driving). He gets 191 years in jail. That's a lot. Particularly for a spree in which no one was seriously harmed.
That said, I'm glad that Mitchell will be off the street. But compare the 191 years that he gets with some of the other sentences given to people who've stolen similar (or much more) amounts. Or white collar criminals. The disparity is pretty high.
But, again: I'm glad Mitchell is off the street.
