Gotta side with the mail carrier defending himself.
Not me! The hours of pleasure these wonderful animals give their urban owners between incarcerations are well worth the life of a mail carrier, or child, or two. It's not like the attacks occur everyday ... just once in a while.
I am not suggesting incarceration for the good doctor for the trivial offence of trayvonning a mail carrier, but should she have to spend a night or two in jail, I think the pit should be allowed to share her cell. BTW, Has the good doctor been checked for rabies?
