Eyewitness identification is lay op

Eyewitness identification is lay opinion testimony.

"I was absolutely positive that he was the one. But I was wrong!"

"I want you to look around this courtroom and
tell us if the man who did this is among us?"

In every criminal case, the government is required to prove the identity of the person who committed the crime. To support a conviction, the government must present evidence that the defendant was the perpetrator or a party to the perpetration of the charged crime. This is generally provided by an in-court identification of the accused; however, it can also be inferred from other evidence.
