I think you’ve got it. If two gangs the size of the bloods and the crips decided to get together and kill cops, there would be a lot of dead cops. This sounds like a PIO doing his job.
I got a text from a cop I work with a few days ago that gang members were planning on killing cops. It came from our Intel Division. One low level gang member gets snatched for smokin weed and he gives up the whole plan so he can walk. That’s usually what happens.
