Just a note that eyewitnesses testimony can be very helpful in most investigations, it just has to be handled very careful. However it often isn't. As you say, lineups can be particularly tricky.

I mention this because often on this topics people say "eyewitnesses testimony is always unreliable!" when actually it's a bit more complicated than that.

Saying that something is always unreliable isn't the same as saying it is never correct. Eyewitness testimony is an important part of any prosecution, but it should never be relied on, and juries need to be informed of the unreliability.
