Would you have found him guilty?
In the first half of the movie, the prosecution acts like they have a slam-shut case against Jeff Bridges. But in my mind, nothing they presented is enough to overcome reasonable doubt. They successfully established motive (he would get his wife's money and business holdings) and to a lesser extent, they suggested intent (his conversation with his lover), though they never showed that he seriously planned to murder his wife.
So all they really proved was that he had a potential motive to kill his wife, and this would not be enough for me. The only other evidence was the witness who said he saw a knife in Jeff Bridges' locker, but to me, that's not convincing enough when it relies on a single witness who only claimed to see a potential weapon, and not a crime in action. Witnesses are notoriously unreliable (and this is shown later in the movie).
So my question is, does anyone here think that the prosecution's case was ever that strong in the first place? Let's ignore how the movie turns out and just focus on what the prosecution presented.
