The Colorado House advanced measures to limit the use of chokeholds by officers and to appoint special prosecutors when law enforcement is accused of using excessive force. The bills, in response to public outcry over allegations of police misconduct in Colorado and the nation, got preliminary approval by the full House Friday. Another vote as soon as next week will send the proposals to the Senate. One measure would allow chokeholds only in self-defense. Law enforcement officials urged legislators to allow chokeholds in self-defense. Another bill would allow judges to appoint special prosecutors in excessive-force cases if a decision not to prosecute is questionable. A person would have to petition the court first. Some lawmakers worry judges considering brutality cases may be swayed by public pressure to prosecute.
