INDIANAPOLIS — Police investigators would be required to record questioning of criminal suspects who were in custody under a proposed rule being considered by the Indiana Supreme Court.

The rule would apply to “custodial interrogations” that took place after a person had been detained. Recordings could be audio, video or digital.

The court said today that its Committee on Rules for Practice and Procedure is collecting public comments on the proposal until April 30. After that, the proposal goes to the justices for a decision.

Copies of the proposal and arguments for and against it may be viewed at the state Supreme Court Web site. Supporters say more than 10 states now have such policies.
