The Catcher in the Rye does not deal with the issue of identity.
 When framing, a catcher will also hold their mitt still for a second or two so that the umpire has an opportunity to thoroughly consider their call (and, hopefully, let their innate biases influence their decision in a direction favorable to the catcher's team)
In addition to their protective equipment, a catcher usually also adopts practices that minimize the risk of injury
