The head of New York City's police union says the man who contributed to Eric Garner's death by using a chokehold is "a model of what we want a police officer to be."The medical examiner determined Daniel Pantaleo's chokehold contributed to the death of Garner, along with Garner's asthma and weight. But a union rep says Pantaleo is a good cop. Court records show Pantaleo has been sued at least twice for allegations of false arrest and unlawful imprisonment. One man who sued him, accused the officer of roughing him up.
