Peckham Rye

The revenue at Peckham Rye obviously needs protecting greatly. Twice this week the revenue protection squad was out in force, flanked by police in illuminous yellow jackets, writing fine tickets and handcuffing people. Last week they were doing an airport style security check on arriving passengers, presumably looking for knives and guns. What was it they used to say at the end of roll call in Hill Street Blues? Be careful out there.
