 I mean, I've come into contact with police corruption quite a lot of times, but perhaps the most significant event I'll tell you about, if you like. Of course. Again, I'll take you back to Nottingham, where I met Cammie. Cammie introduced me to one of the gangsters who was in the team of Collin Gunn. About four and a half months into the operation. The day after that, two of my backup team went off sick. So I got two new people to come onto the team. I met the first one, Chuckie's hand had no problem with him. The second one, Chuckie's hand and the hairs just went up on the back of my neck. When you've been on the streets day after day, feeling at risk, your senses are quite fine tuned. You're really sensitive to body language and this guy was just wrong. So I spoke to the boss and said, look, boss, I can't have this guy knowing what I'm doing. So he excluded them both, so they didn't ask any questions and they never found out what the job is about. Twelve months later, Collin Gunn is brought down. Brilliant work by Nottinghamshire Constabulary. And it was found that that carp that I had taken exception to, a guy called Charlie Fletcher, was an employee of Collin Gunn. He'd been paid to join the police and he was paid £2,000 a month on top of his police wages for information and bonus bonuses for good information. By the time I'd met him, he'd been in the police for seven years, seven years. You can look him up, the newspaper stories of his conviction as online, Charlie Fletcher. Now I have to make something really clear. That kind of corruption can only be paid for by the money from the illicit drug supply. There's two reasons for that, one, there's more money in the illicit drug supply than anything else. Two, the way we police drugs creates monopolies. See, police are really good at catching drug dealers. Brilliant at it. They'll catch them day after day. They'll catch twice as many if you give them twice as much resources they will do, but they never shrink the market. The market never reduces, ever. You arrest the drug dealer. You just create an opportunity for another one or two more. So by policing drugs and arresting people, you thin out the competition for the most successful gangsters. And in fact, the best gangsters use police informants to get rid of the competition. The police do the business for them. Is there a lot of high profile gangsters who are snitches? I believe there's a lot of informants out there who don't go to prison because they're also working with the police. Do you see that a lot? A lot of high profile names giving the police information to keep them off their back, but also jail the competition around them. That's exactly how it works. And in fact, there's a chapter in drug wars where we interviewed a guy called Frank Matthews, who was a high profile informant handler in the Met, and he realized the extent of police corruption. And he started reporting on it, whistleblowing. He'd put so many gangsters in prison. He'd chased organized crime, all of his career, only at the point when he started grassing up fellow police officers, did he realize his life was in threat. He thought he was going to get murdered. And in fact, he had to be snatched. He had to be taken away and put into witness protection to protect him from corrupt police.
