I have had to google them, they have a few open days coming up so may be worth a look. They say on their site that they try to avoid traditional vehicle based surveillance methods. I don't know how they will manage that and if you are operating on your own to start off with this aspect of surveillance will be important. In relation to the thread you posted people couldn't reply with a post for some reason hence the lack of posts. Also your private message facility is blocked. If people want to give you a private mesage they have to send it to visitor messages which are open to all. You are not pestering me at all, glad to help out. I do know that Peter Jenkins is second to none. Pick up one of his books, always useful as a reference guide as well as a learning tool. 'Covert Surveillance'., 'Advanced Surveillance', and I was told yesterday that he has a new one out. Should be listed on his web site. Regards MW.
