"Amri had been identified by security agencies as a potential threat and rejected for asylum" Western Justice  and security must get real about the threat of  jihadi terror. Catch & release justice must end. It must be acknowledged that  'radicalization'  in prison and elsewhere occurs only to people who first take the leap of faith to declare Mohamed prophet of God. Therefore ban Islamic rituals in jails. No Halal food. No prayers. No Muslim chaplains. "Real" Muslims don't end up in jail anyway.
