Unrealistic Scene *Spoilers*
When Rupert and Brandon were struggling for the gun, why didn't Phillip help Brandon? He could've done something to prevent Rupert from getting the gun. They were struggling for at least a minute. Plenty of time for Phillip to attempt something knowing if Rupert got possession of the gun, it would mean the end of his life or freedom for all intents and purposes. (Desperate circumstances call for desperate measures). Instead he presumably stands there doing nothing and allows Rupert to gain possession of the gun. I thought this element of the plot was not realistic.
