They can get an idea of guilt or not based on body language. I have never said it can be used in court or claimed it but if somebody is accused of something then talking to them is a good place to start whether there is a no comment or not.
You were trying to make out that police didn't try to read body language in interviews, summed up by this:
Here you go again, trying to pick up and focus on individual words. Much like the whole "dropping legals" situation where everybody else knew what was meant bar you.
All I said was even if they just say no comment, that police can still pick up on reactions and body language. I never once said it could be used as evidence or in court.
A bit boring really.
They can get an idea of guilt based on body language! Oh, this just gets better.
So, just to confirm, they can get an idea of guilt but can't use this information in any format. So that's really useful then isn't it.
Also, I wasn't trying to make out anything.
Despite searching you couldn't find any reference to reading body language being a policing technique used in interviews, despite you saying I should "email the police who carry out training in reading body language".
You've made comments and I've simply pointed out they don't stack up.
Also, just to clarify nobody has been told to drop legals.
