Poor Movie - big plot hole.
The scene with Terry giving evidence in court was unbelievable. When the defense lawyer pointed out that Terry wore contact lenses and could not identify a book from the other side of the court and therefore could not have worn his lenses in bed he could not have seen the crime why didn't Terry simply reply, 'Yes your honor, I wasn't wearing my contact lenses but when I heard the scream I put on my glasses before looking out of the window so my vision was normal.'
After all I don't know of anyone who wears contact lenses (particularly someone who is extremely short sighted) that does not also own a pair of glasses that they put on after they have taken out their lenses.
