Only because of the other people in there. We should probably work on that, too.
The bible thought you should investigate murder by sacrificing a cow and saying, "not our fault."
So leaving that aside, most accusations aren't false in so much as they are MISTAKES.
For instance, the execution of Cameron Todd Willingham. He was accused of burning his house down and killing his three daughters. In reality, the science that found "Arson" was severely flawed. Witnesses make mistakes. Police are sure about a suspect and don't investigate other leads.
