Prison officer chiefs say Muslim prisoners in one jail were exempt from searches by sniffer dogs after they complained on religious grounds. Shockingly this is at HMP Frankland, the same high security lock-up where warped Manchester Arena terrorist Hashem Abedi viciously attacked four guards last week. If the evil Abedi exploited this ruling to hide his improvised weapons safe in the knowledge he could evade security checks there will rightly be public outrage. How did it come to this? Courageous prison officers who daily have to deal with violent Islamist extremists should never be exposed to risks in this way. Too often virtue-signalling bosses in the justice system are bowing to the demands of dangerous inmates. This madness is fuelling a rise in Islamist gang rule behind bars. Many of Britain’s crumbling and overcrowded jails are already tinderboxes waiting to erupt. The safety of frontline staff should always come before the wishes of terrorists and murderers. As former prison governor Ian Acheson says, their welfare cannot be compromised because prison bosses fear accusations of racism.
