I assume nothing about individual officers of the law. My husbands best friend of many years is a cop and as far as I know a clean one.
But just because an organization of Law Enforcement says "so and so is guilty as hell" we are under no obligation whatsoever to assume that is true. Just because they may say 'this and that happened in this case' we are under no obligation to believe them. It is up to a jury to determine if the police have done their jobs diligently and without an agenda.
