5 Ways to out a liar

1. Ask questions with the presumption of guilt. In this country you are presumed innocent by the court, not by your interrogator. It has been shown to be 97% effective. Law enforcement does this all the time, so don't let them accuse you of being "treasonous" if you do the same to them. A man was gunned down in a predawn raid. Presume that it is cold blooded murder until they provide evidence it isn't.
2. Ask open ended questions then close ended.
A person who is telling the truth wants all the facts out there, they will want to answer close ended questions with more than a yes or no. Liars want to say as little as possible. They will attack you for even asking a question. Think about that, a 70 year old man, never convicted of a crime, is gunned down in his house and murdered and we can't ask any questions? That doesn't bother you?
3. Ask the story in reverse
We are not talking to the men involved in the raid so this may not seem relevant. However, if you are coaching someone to lie you need time to go over all the questions, get them to practice saying it in reverse, make sure all the accounts are the same and align with body cam footage, and you can always give yourself an out by saying "I can't remember". That is not plausible a day later, but a week later, a month later, so the reason to ask all these questions immediately is to prevent them from concocting and rehearsing a story. All criminal interrogators know this.
4. Ask unexpected questions
Again, we aren't allowed to ask any questions and are told to sit tight a week later. We are not given an opportunity to ask an unexpected question.
5. Videotape them when you ask the questions.
We all have micro expressions we can't control. Only the very best liars who have rehearsed and also take muscle relaxers and have been coached can insert reasonable doubt when examining microexpressions. If you notice they never brought out the people involved in the shooting to talk. This is not accidental. If I were a lawyer I would be very concerned about allowing someone who might be held on trial to come and speak to the press, even if they were innocent.
However, a police chief, someone who has interviewed everyone and seen the body camera footage, if he is not someone who might go to trial, he should be willing to come and talk freely, answer all questions, and put any concerns the public might have to rest. All these and many other questions should have been answered a week ago.
For example, consider the Press secretary for the President. Their job is to give daily press briefings because the people have a reasonable concern about things that are happening and things the president is doing. If you are honest and not lying you are happy to entertain all questions even if at times you will have to get back to the person with the answer (they asked an unexpected question) or the topic is classified and you can't answer it in public. We have all seen exhaustive and comprehensive press briefings and press briefings where the person is clearly afraid to answer because they know the official story is a lie.
We have excellent people who are trained in body language and micro expressions. No liar wants to get on video with their lie because you can examine it frame by frame.
So to me it is a big red flag when something like this happens and they don't give exhaustive and comprehensive press conferences immediately (within 24 hours). Someone trying to get the truth out would welcome the opportunity, only a liar trying to cover up a crime would avoid doing this.
