It is unlikely that Dirty Harry or Starsky and Hutch will interview suspects as politely as Morse or Frost. Somehow you just know "feeling lucky, punk?" is not going to be abandoned in favour of "cuppa tea, sir? Now tell me in your own words what happened".

Forensic psychologist Ray Bull, of Leicester University, is not holding his breath about changing police interrogation procedures in the US, but he is pointing out to an American audience that the less confrontational style adopted in England and Wales in recent years works as well, if not better, in securing confessions, and is less likely to lead to miscarriages of justice.

Squirrels emit 'silent scream'

While studying the little rodents, researchers noticed that some of them made faint whispering sounds, as if they had lost their voices.

But when these "silent screams" were processed by a bat detector, an abundance of ultrasound was detected.

The researchers believe the whispers might be "secret" alarm calls - that the squirrels' predators cannot hear.

[...] James Hare and his colleague David Wilson analysed the high-pitched calls, and found they were made in reaction to a threat; and elicited an alarm response in other squirrels.

Richardson's ground squirrels also make audible alarm calls, which seem to raise a more dramatic response in the "audience".

So the researchers speculate that whisper calls might indicate a slightly lower level of threat.
