Investigators welcome partial recording of interrogations
(Mainichi Japan) June 30, 2011


TOKYO (Kyodo) -- Most police investigators welcome the introduction of partial audiovisual recording of interrogations as being "effective in demonstrating that a suspect confessed voluntarily," the National Police Agency said Thursday.

The announcement is based on the NPA's two-year trial from April 2009 of partial recordings of interrogations in which suspects admitted to allegations against them.

In the 717 cases, investigators in 696, or 97.1 percent, expressed positive views over the partial recordings, saying they clearly showed suspects confirming the contents of investigative records by nodding yes or voicing their consent, according to the NPA.

The recording shows interrogators reading a suspect an investigative record and in some cases correcting it at the request of the suspect. The average recording time is around 15 minutes.
