Uhm, the rioting in Baltimore is national news. Comments about the riots, especially controversial comments from an officer of the court, are going to be national news, as well.
You're the one who wants to see racism in it and are eating it up. The quote was about law enforcement being judge, jury and executioner rather than due process.
Actually, the very beginning of the quote she provides the full context herself with "So I am watching the news in Baltimore..." It's a direct reference to the rioting that was going on, and she made the Facebook post at the time the rioting was going on. She's not making some general statement about throwing bricks, she's making a statement about what was going on in the rioting, and her solution was to skip the arrest and the rest of the judicial process and just shoot 'em.
No, THIS refers directly to "protesters to turn violent," which includes both the brick throwing and the "etc."
It wasn't sloppily written at all. It just doesn't give the narrative you want it to give. The Washington Times link provides the full quote and the full context, and the story is the same story as the original link I provided and the Reuters piece you countered it with. None of the stories linked by your or me even mention race or racism. That's all you. You, for some reason, want to remake the narrative into being about the news media running stories of perceived white racism to advance an erroneous narrative, but none of those stories do anything of the kind. The story is, an officer of the court thinks people who throw bricks at police officers during a riot should be shot without arrest, charges or a trial, much less a jury being present. That's it. That's all there is to it. That's the full context of her statement.
