Animal welfare groups, including New Yorkers for Clean, Livable, and Safe Streets (NYCLASS), have roundly criticized not only Martin's admissions, but the pride he takes in his violent actions.
"It's an outrage that Norman Martin - in his own words - admits to abusing and torturing horses when they don't do what he wants," NYCLASS representative Allie Feldman told The Dodo.
"We are shocked by the admissions he makes in his book and urge authorities to monitor the horses in his care - horses that are clearly in imminent danger," she added.
Despite continued abuse and a disturbing number of traffic accidents, horse carriages continue to operate in and around New York City's Central Park. Last winter, carriage horses were forced to work through every single snowstorm despite treacherous travel conditions.
