Certainly, as Commander Mainville and Chief Inspector Latulippe have noted, street gangs are very fluid. They change naturally, quite aside from any efforts they might make to avoid the consequences of being on a list. Assuming you could feasibly put them on a list to start with, they would be constantly changing. Names change, personnel change, groups splinter. The “Fresh Off the Boat Gang” spawns the “Fresh Off the Boat Killers” as a rival gang, but the personnel of the gangs.... The names are known to the police, but the personnel are certainly fluid, and they change. That would certainly be a concern, in terms of whether or not the name on the list would clearly designate a group of people at any given point in time.
In addition to that, the very fluid nature that has been painted would mean that much, if not most, or if not all, in some cases, of the kind of evidence that has been discussed—and we're quite aware of the burden involved in presenting that evidence—would still have to be presented in any particular case to show that in this case the accused committed extortion, say, in connection with a group of people that constituted the organization on the list.
Commander Mainville talked about updating the leadership and so on. Well, as the leadership changes, there will always be a challenge as to whether or not the group is still the same one as the one that was designated on the list. The connection still has to be shown; that is not avoidable, in that the case still has to be made that the person committed whatever the offence was for the benefit of, at the direction of, or in association with a criminal organization. The starting point is proving that a criminal organization exists, but then the connection has to be shown. The evidence for proving both of those things is very much the same in many, if not most, cases.
So whether or not it could change itself in order to avoid the name, say, on the list, it would do so anyway just organically, because they're flexible organizations. Beyond that, there would be an issue as to whether or not the particular group in any particular case was whatever name was left on the list.
