There are videos of protestors marching chanting over and over and over:
"What do we want? Dead cops.
When do we want them? Now!"
Two police officers shot. The message 3 hours before this by the murderer?
“They Take 1 Of Ours . . . Let’s Take 2 of Theirs,” the post continued, ending with, “This May Be My Final Post.”
Clearly links it to the protest issue.
Does that chant cross the allowed free speech? What about A group marching chatting they want dead black people? Dead gays? Dead Muslims?
I think it does. It is clearly attempting to incite violence. I would argue it is a terroristic threat. That they "want" it shows intent. That they "want" it "now," means its tangible and imminent.
If people can chant they want cops killed now, any group or anyone can want anyone individually or by category killed.
