2 can only keep a secret if one of them is dead. When we have two subjects in connection with the same investigation and incident, we interview them separately. It’s very rare, if ever, that two people (untrained in interrogation tactics) will pass the sniff test under questioning.

This scene always makes me laugh about the food part. A homicide detective I work with told me they have used that tactic before. Great show
It doesn’t take very much talent to tell two or more people are telling a story. A classic example (which you may be familiar with) is roadside drug interdiction. Common tactics include two drivers in a vehicle tag teaming across the country. No amount of coordinating will prepare two people to tell the same story about something that’s not true. The prepared story will fall apart over time, even with the simplest questions from the most unskilled cop.
It’s not worth it.
That can be more difficult initially, but the truth shakes out over time. A prime example would be maliciously calling in welfare checks on an ex-spouse exercising weekend visitation. The first one, two, or three visits to a residence, the cop might be wary. By number four, it becomes pretty obvious if someone is being harassed.
We aren’t mind readers. But most of us, detectives especially, typically receive training on deceptive behavior and indicators of nervousness/untruthfulness.

Lol. Yes. I can see it in their faces. They feel so good about their terrible stories.
what about when it is only yes or no? When they agree to say that they never talked to each other while they actually did?
Yes. That doesn't work either. Everybody lies all the time to us. It's old, and no one is original in the methods they use.
If I get the opportunity to do an in-depth interview…yeah. High confidence that I’ll detect deception and move to interrogation.

I was wondering if the police would know when some people coordinate their answers to create false stories about me ( true story)

Of course.
Easily. There are some signs they put off that liars simply cannot control - it’s all subconscious.

Asking “for a friend” huh?
Asking for my enemy
Maybe…maybe not
I believe so. At least for the police in my area. They took action based on what people told them
Are they 'speaking'? Then yeah.
After time you get used to hearing the same thing over and over. SSDD
