The Handcuffs
I'm not even going to argue about whether Ellen should have cut the cuff chain or the hand. His death was warranted.
If I had a problem with the handcuff dangle scene is that he looks like he weighs 220 to 250 pounds. I'll modestly say 220. Sarah might weigh 120 pounds tops. She would've gone down like home values in 2008. They couldn't have grabbed her soon enough.
If I were to grant Sarah the ability to hold up the sheriff her wrist couldn't and I don't care what she weighed. People have cuff bruises when they're put on too tight, imagine if 220 or more pounds were pulling on those cuffs.
