“why the National Guard hasn’t been sent in long ago”
That would be racist.
What killings? I don’t see any killings.
The National Guard wouldn’t be allowed to carry, or use, AR-15’s, M16’s, M-4’s or a peashooter in Chicago. Might offend the street killers, white liberals, white communists, black extremists, and snowflakes in the universities.
And what about the innocent decent people of Chicago who are going to be gunned down by the street trash? For the Left, white and black and Marxists, it is “ Never Mind”.
