Sorry, posting tidbits and snippets don't qualify. If you want to discuss a particular case then lets have all the facts. The opinion of one lawyer doesn't constitute a fact.
Commonwealth v. Peppicelli. If you worked in a DA's office, then you can find the recordings of the oral arguments for the appeal. Listen to it and weep.
And guess how favorably judges look upon statements obtained by police based on lies.
Sorry, but the courts have held that police can lie to suspects. It is standard police procedure and happens all the time. For example:

Standard procedure when you have two perps is to separate them and tell each one that the other is rolling over on them. The courts don't have any problem admitting the resulting confession.
Why. I hear this, but I still wonder why. If police roll up on a situation where you are standing there with your pistol standing over some dead guy and the only thing out of your mouth is you asserting your right to an attorney and the right to remain silent, you've certianly preserved your rights, but you've also made things massively difficult.
Yes. There was a lengthy discussion in the seminar about what you should or should not say in the aftermath of such an incident. The panel of four split two and two about what to say.
The two defense attorneys (one a former prosecutor) said you should STFU and say you need to speak with your attorney. The former prosector was an ADA in Suffolk County (Boston, MA) for 13 years, during which time he prosecuted thousands of cases. When he left the DA's office, he had over 100 attorneys reporting to him. He has been a defense attorney for 5. The other attorney, Kevin Reddington, is one of the most prominent criminal defense attorneys in eastern MA. He successfully defended Charles Chieppa:

He also represented Dr. Ann Gryboski.
The police chief and Attorney Lisa Steele, a prominent MA and CT appellate attorney, suggested that you make a brief statement to police, saying what happened, pointing out evidence and witnesses.
The big problem that they all agreed on is that in the aftermath of such an incident you will be completely wired with adrenalin and will likely not be that coherent. The effects of the adrenalin can change your perception of time and distance. So your perception of what happened may not be consistent with the forensic evidence. For example, you might tell the officers that the guy was almost right on top of you with his knife when you shot him, when forensics show he was 15 feet away. Then the police think you are lying and things go downhill from there.
I have had large adrenalin dumps on two occasions (that fortunately had nothing to do with self defense). I can attest to the fact that I was not thinking clearly at that time.
In any major US city, the police union's contract typically specifies that in the aftermath of a shooting, the officer involved must be taken to the hospital and does not have to speak to internal affairs until at least 24 hours after the incident and will only do so with his attorney present. There's a reason for that.
Here's excerpt from an article by Attorney Steele:
Oddly, four out of five suspects questioned by police routinely waive these rights and agree to answer the investigator’s questions. Investigators are taught how to create a rapport with a suspect, offer sympathy, minimize the importance of the Miranda right, and persuade suspects to waive their rights and speak with them.

Kassin suggests that innocent people have a naive faith in the power of their
innocence to set them free. They may think that investigators will accurately judge their actions and thoughts. Sadly, studies have shown that law enforcement officials are no better than the rest of us at telling truth from lies.
Police officers see a difference between an interview – a neutral conversation
intended to get information about a crime before an arrest, and an interrogation – a post- arrest confrontation intended to gain a confession. In a self-defense situation, you may be arrested at the scene. In a self-defense situation, you will be admitting to intentionally using deadly force against the aggressor. The legal line between lawful self-defense, voluntary manslaughter, and murder can be very thin; much may depend on what you say to police and your words may be dissected by lawyers, judges, and jurors for years to come. In the immediate aftermath of a shooting, you will not be emotionally prepared to give an accurate statement.
