How Do Line Ups Work?

How reliable are eye witnesses? If yu've seen another funny moviy l touh im. Not going to talk about it. Here is my cousin, vinnie. There was an article not too long ago talking about line ups. They should be done somewhat like an experiment. The people who are in the room with the victim, when the victim is looking at the line up, they should not know if the perpetrator or perpetrators are in this particular group. You can't give the defendant any kinds of body language that might indicate that one of the bad guys is in the list. And so the ideal way to do this is this somewhat double blind kind of situation.
