Christmas: for most of us, it's a time of joy and celebration. But for a new group of organised criminals, Christmas means opportunity. Retail crime and shoplifting have hit record levels in the last few years - and the festive season is when this issue is at its worst.

So when did shoplifting go from petty crime to serious business? When did retail criminals turn from hard-up addicts and opportunists, to gangs with getaway cars and balaclavas?

In this episode, Andy and Neil explore why shop theft has become so rife, and what needs to be done for the police to regain control of Britain's high streets. They hear from two experts on different sides of the problem: Cullen Mais, who was once the country's most prolific shoplifter, and is now reformed and working with retailers to catch thieves. And Lucy Mitchell from the New West End Company, which runs private security for many of London's busiest shopping streets.

What proportion of 999 calls in the UK are genuine emergencies? The answer will shock you.

In this episode, Andy and Neil play you some of the most bizarre and ridiculous 999 calls which have been made in the last year - and explain why these hoaxes and time-wasters could ultimately be a matter of life and death.

They also take you behind the scenes of an emergency response room to explain what happens when a genuine emergency is called in: who answers the phone? How quickly are officers deployed? And who decides whether firearms backup is needed? Plus, Neil reveals the top three most memorable 999 calls he responded to in his days as a PC.

Andy and Neil also discuss what it takes to deal with the unique challenges of being a response cop - and whether it's time to take tougher action on those who waste police time.

Why do less than 3% of all reported rapes in the UK lead to a conviction? Andy and Neil describe that statistic as "shameful" and "a scandal" - and attempt to explain why a combination of rape myths and problems in our creaking justice system make it so hard to prove someone's guilt.

Plus Andy reveals why one senior detective he's spoken to believes it's time to get rid of jury trials in rape cases - and why using lie detectors could be part of the way forward.

Plus Andy and Neil are joined by Jade Blue McCrossen-Nethercott: a rape survivor who was so badly treated by the justice system that she took legal action against the CPS - and won. Jade tells her story, including the extraordinary reason why her trial collapsed, and explains what she is doing now to work with police and prosecutors to improve the way this issue is handled.
