pizza-parlour justice
n.— «Two-for-one credit, also known as pizza-parlour justice, should be another target for reform this year. That’s where inmates are credited double-time for pre-trial custody, which makes no sense. Criminals play the system and stay in pre-trial custody as long as possible to reduce their overall time behind bars.» —“Justice reform Phase 2″ by Tom Brodbeck WInnipeg Sun (Manitoba, Canada) Mar. 5, 2008.
