In response to the prosecutor’s questions, a lay witness who is a high school graduate testifies as follows: “I measured the defendant’s skid marks, and I believe he was driving at a speed of at least 65 miles per hour.” “In my opinion, anyone who drinks two beers becomes intoxicated.” “When I saw the defendant right after the accident, his face appeared flushed and he staggered as he walked.” “My sister told me that the defendant did a lot of drinking at the nearby bar.” What objections should the defense make to each one of the witness’s statements?
