1.Discuss the challenges presented by eyewitness testimony. What techniques can be used to reduce misidentification by eyewitnesses? What other investigative steps can be taken to help corroborate eyewitness testimony? Knowing there are these challenges with eyewitness testimony, why is eyewitness testimony still important to investigators?
