I don't see how this isn't on topic, and I'm certainly not being passive-aggressive with you, I was just pointing out that Interpol don't do what you say they're doing. I mistakenly thought you were aiming for realism (and there's no harm in not doing!!) and I just wanted to help. My apologies for spelling your name wrong also.
Regardless, NCB agents are just points of contact as it states on their website and NCB ones (for instance http://www.interpol.int/Member-countries/Europe/United-Kingdom), although they do occasionally assisting with operations in an advisory/training role they do not lead or assist in an operational/field role.
I can't argue with you if you're saying that you did get a lot of useful information back from them, just that you're very, very lucky.
I'm not looking to get in a pissing match with you but I can't tell if you are intentionally trying to be daft while arguing this point. Even the link you provide and the stories on that site both provide explicit evidence that they do indeed do exactly as I have stated and exactly as several representatives described it to me in interviews. For your benefit, I will provide some highlights:
"The INTERPOL National Central Bureau (NCB) for the UK is part of the National Crime Agency (NCA), a powerful new body of operational crime fighters with the responsibility of leading the UK’s fight to cut serious and organized crime. The NCA addresses national threats and incorporates the functions of numerous former UK organizations, agencies and units in order to:
Tackle serious and organized crime;
Strengthen UK borders;
Fight fraud and cybercrime;
Protect children and young people.
The NCA also provides a range of support services to police forces and law enforcement agencies across the country, including the services provided by INTERPOL Manchester." Please note in particular the line "body of operational crime fighters with the responsibility of leading the UK’s fight to cut serious and organized crime." which contradicts your claim that they do not lead investigations or provide operational/field role. I'm not sure why you are hellbent on trying to discredit the information I spent months painstakingly collecting while you think your 10 minutes of skimming (incorrectly) a webpage. However, in case providing the information specifically from your own "evidence" wasn't enough, here are a few more links -
http://www.interpol.int/News-and-media/News/2010/PR014 and
http://www.interpol.int/INTERPOL-expertise/Response-teams. There are many more of course. You are correct that they primarily provide training and logistics, but claiming that they do not operate in the field, leading investigations and coordinating arrest teams is irresponsible and offensive.
