The really grim irony is that Dallas' PD seems to be one of the most reform-oriented in the country. Tons of tweets showing them mingling with protestors, reports about mutual respect between them and reformers. Terrible, terrible thing.
Just like the Red Brigades had to kill Aldo Moro, of all DC leaders.
Yeah, just like how the Detroit riots happened under Jerome Cavanaugh, who had a reputation as one of the most progressive and reform minded. Or how the trades unions declared war on the Callaghan government in '78-'79. All of these preceded sudden sharp turns to the right and historic losses to the perpetrating parties that they never recovered from.
