I am a law abiding citizen, always have been and always will be. However, I do have a friend who has been involved in aspects of organised crime and met up with him about a month ago. 

I am aware that he has been involved in certain criminal activities, processing goods and such. It is not my business and I have never pryed further.  Although, I stay on the side of the law, I have no great regard for the police and no certainly desire to aid them. 

So recently, my friend shows me a picture of the group he hangs out with (they did a paint balling session). One of the faces I recognise, as I have organised deliveries (I am involved with logistics) as being a police officer. 

I tell my friend this, and say that it seems somehow a police officer has got into their group and say nothing more. Maybe, the cop is just a friend and not undercover but I feel my friend should be informed. 

My friend is surprised but thanks me for the information. We leave and won't see each other again till next Spring. 

Since, I am not involved in organised crime or any crime in fact. I see this as just one friend informing another and nothing more.
