It is difficult to determine. If we are talking about street gangs that commit traditional crimes, there are maybe 20 or so. We have to remember that there are also Asian criminal groups, and Middle Eastern, that are emerging now, and that police organizations have not tackled to a large extent, but they are here and we know about them.
The intelligence services supply information to us about that. These are evolving groups, but for the ones we are most concerned with there are at least 20 or so.
