Interviewing an eye witness is the most legit form of evidence.
Having an eye witness on the stands can help to prosecute a criminal.
If the witness lies on the stands, they are committing perjury they will serve time themselves. Therefore, eyewitnesses are more apt to tell the true recollection of what happened.

I will not edit someone else's answer. However, this is incorrect. Eyewitness evidence is NOT the most legit. In fact, it is the least. However, it is very important for giving a lead, but you will not just stop there in an investigation. There still needs to be direct evidence found. You cannot solely rely on one's memory or recollection of an event. Interviewing an eyewitness is beneficial for taking field notes in which will be used in court but you must have tangible or direct evidence as well.
