"PS - I note you have also ignored my many quuestions ... why is that? "

Er, because there are so many, buried in long, multiple posts.

The crime we are discussing is street grooming.
Only BP gangs have been shown to be doing it.
That is probably significant.

No one has just looked at BP gang crime and said "BP gangs are doing these BP gang crimes."
We are saying "why are BP gangs and no one else doing these crimes?"
