Because they want it to be.

They want us to turn militant and violent against law enforcement.

If you believe the psyop, then you believe that un-armed Ashli was shot to death by an armed government officer of some kind, and that officer never had to answer for it. It is designed to evoke rage.

Because they want to show the normies that we are violent, dangerous extremists.

And justify shutting off our internet, freezing our bank accounts, etc.

It is similar to why Jussie Smollett had to resort to faking a racist MAGA attack. It was done out of frustration that we weren't really doing anything racist.

I think BLM was expected to turn us all into radical White Supremacists. That is why there were so many black-on-white violence videos. All designed to make us hate black people and start to fight back. But it really didn't work because we saw through it. You notice how the BLM violence turned off like a spigot? It wasn't organic. It was a funded program.
