Japanese investigators have banned smoking in interrogations.

In Tokyo, police decided to conduct an experiment during which the premises where the interrogation of suspects would be barred from smoking. As reported by Reuters, referring to Kyodo News, the experiment will begin in mid-February 2009 and will last three months. If the police leadership will remain satisfied with their results, the ban on smoking will be introduced permanently.
The Tokyo police decision for two reasons. First, the desire to rid the smoke non-smokers who are present at the interrogation. Secondly, the police came to the conclusion that if the investigator offers the suspect a cigarette from his pack, he may take it for a sign location.
It is noted that in 2008 the Japanese authorities issued an order that investigators not to touch the suspect during questioning, but also to interrogate them for a long time. The ban was issued after several cases in which people are admitted his guilt, does not withstand the pressure and then found innocent.
