Actually, read the opening post again. Bentley told the other cop to check the handcuffs. Bentley meant they were too tight but the cop mistook him and thought he was saying to tighten them even more.
Just one example of how people can mistake what other people say.
Indeed. You have provided a good example of somebody mistaking what both men said.
Btw where does it say that Walker mistook Bentley? And why was Bentley smiling when he retold the story?
