Considering the way many cops are behaving these days, this may be a good idea for all of them as a requirement for continued employment.
That might not be a bad idea.But in *this* case it must be noted that a cop isn't a brain specialist and cannot be expected to think like one...he can only be expected to take what he sees at face value.If,by chance,my hunch is correct the prosecutor would be duty-bound to refuse to prosecute.If he carries on with the prosecution than the judge is duty-bound to dismiss the charges.And if *that* doesn't happen then it's up to the jury.
