Witness testimony: Around 8:00 on the morning of Tuesday, July 6, I saw a man exit from the back entrance of the building. I knew it was McGregor by the man's height and his long, slightly awkward steps, and from the fact that he was wearing a hat—possibly a baseball cap. McGregor always seemed to be wearing some kind of hat. On Tuesdays there are always several groundskeepers scheduled to work on the grounds, and he would very likely have been scheduled that day.
Select Assumes to be true for the statement that describes something the testimony implies the witness assumes to be true, and select Assumes to be false for the statement that describes something the testimony implies the witness assumes to be false. Make only two selections, one in each column.
The witness identifies McGregor based on three characteristics: height, gait, and wearing a hat. For this identification to be valid, the witness must assume these features distinguish McGregor from others. The witness explicitly states that several groundskeepers work on Tuesdays, contradicting any assumption that McGregor was the only one scheduled.
