"In what way are they better informed, or remotely as well informed, as CAIN?"

Possibly Keith, because they painted a picture that Jim preferred.

Wonder if the HET took Section 3 of the Criminal Law Act 1967 into account or did they just rely on THEIR interpretation of the "Yellow Card" ROE?

Criminal Law Act 1967 - Section 3

3. Use of force in making arrest, etc.

(1) A person may use such force as is reasonable in the circumstances in the prevention of crime, or in effecting or assisting in the lawful arrest of offenders or suspected offenders or of persons unlawfully at large.

(2) Subsection (1) above shall replace the rules of the common law on the question when force used for a purpose mentioned in the subsection is justified by that purpose.

Still on the "Cook" thing JOM - wonder what it is that you have against those engaged in the catering industry - apart from that, it just serves as another item in rather a long list that you are totally wrong about. As to trawling through past threads to find examples of abuse being hurled I could do the same targeting your spittle-flecked rants and temper tantrums and guess what? The list I will be able to produce will be damned sight longer than yours JOM, you will also find that in the exchanges yours will predate mine.
