The city's police commissioner and Patrolmen's Benevolent Association spoke out Tuesday against a bill proposed in the State Assembly that would require police to only use the minimum amount of force against suspects.

The measure would require police officers to use weapons with intent to stop, rather than kill a suspect.

Police Commissioner Ray Kelly says requiring officers to use non-lethal force is impractical because officers are nervous and their adrenaline is flowing when they are trying to subdue a violent suspect.

"It's just something that, that can't work. This bill has been around in various forms for years. It's just simply, it can't be implemented," Kelly said.

Currently, state law affords an officer the right to kill if he or she feels someone's life is in imminent danger.

Patrolmen's Benevolent Association President Pat Lynch called the legislation unnecessary, saying New York City Police Department officers are already mandated to use the minimum amount of force to affect an arrest.

He also said NYPD officers are the most restrained police in the world.
