I agree. For example, if police falsely said they were looking for a 2011-2013 car, hoping to give him a false sense of security, defense could eventually claim "our client does not have the type of car you said you were looking for, why have you brought him in?" If they then say well we were mistaken, we just thought it was 2011-13, the defense could call into question the quality of the police work. Just as an example, no idea if that happened here.
Now if there's other evidence, that may not matter, but why would the police deliberately set up easy defense objections? It just seems fanciful that police would play the proverbial 3D chess with a suspect. MOO
