Best Answer

At the time of cross-examination the witness will be caught.

Added: By virtue of the ciminal investigation which led to the arrest and charging of the defendant(s), the prosecutor pretty much already knows the facts of the case and can generally tell when a witness's statements stray off into deceptions or outright lies. When a prosecutor questions a witness he is NOT guessing at what the witness's answer might be, he already knows what it should be.

Can a prosecutor motion for suppression of evidence that would prove their witness is lying and was generated by the police department?

I've read the question four times but can make no real sense of it - so I'll try to break it up and answer it in segments.(1) Yes, the prosecuter can make a motion to the court for ANY reason, just as the defense can. They will explain the motion, based on law, and the judge will rule and either grant the motion, or not.(2) WHO alleges that the witness is lying? If the witness is lying then the defense counsel has the right to impeach them under cross examination, so I don't see what the problem is.(3) I'm unable to make head nor tail of the police department's alleged involvement in this scenario. What, or who, did they "generate?"

Lying means to tell a lie, whereas bearing a false withness means to carry that lie futher. When we hear rumors we should not speak them unless we know them to be true because the rumor maybe a lie and if we "gossip" about it or carry it to the next person, we have become bearers of a false witness.
