Looking online I can only find two instances of serving police officers committing murder in the UK, so I don't understand how Farage's comments on the Couzens case are relevant to whether two-tier policing exists. One concerns an individual crime; the other is a claim about policing as a system.
At least 16 serving or former policemen have killed women. For a man who claims to want to protect women (same as Yaxley), they've a funny way of showing it...
These are their names, if you're interested...
