Protests have the power to change the political landscape and history is proof.An assistant professor who studied unrest in the 1960s says how things change is determined by the way protesters share their message.“When the tactics on the ground, which are essentially telling a story, tell a story that focuses our attention on rights, on injustice, then that's what the media emphasizes,” said Omar Wasow, assistant professor at Princeton University. “Civil rights, you know a redress of grievances, and those kinds of stories can powerfully move politics.”Wasow researched protests during the civil rights movement. He found during the early 60s, the wave of peaceful protests led to public opinion favoring their message and legislation getting passed. But later protesters became more violent and public opinion shifted again.“What we saw in the 1960s was that you can trigger a kind of backlash movement in which the taste for law and order, a kind of more police-centric narrative comes to the fore and that's going to make it harder for folks who are trying to push for reform,” said Wasow. Wasow says politicians were able to capitalize on that anxiety, like when Nixon won the 1968 election.While we don't know yet how much of an impact there may be this year, Wasow sees a lot of similarities between then and now.He thinks reforms are possible, if protesters keep attention on inequalities in the criminal justice system and state violence. 1463

Special counsel Robert Mueller's 22-month investigation was an often-shocking story about what Russians, Trump campaign associates and others did in the 2016 election so their preferred candidate could win.Now that investigation is complete. And the public, the media and Congress are anxiously waiting to learn what more, if anything, Mueller uncovered, and how much Attorney General William Barr will make public.Mueller's office has been notoriously silent, choosing instead to speak almost exclusively through court filings -- and with Mueller slipping out of his office unseen on Friday afternoon with no public statement to make and no more indictments to bring.The only public message, through a spokesman, was that Mueller would finish his service as special counsel "in the coming days" and that the office would be closing.However, what Mueller has revealed in court has already told the story of Russia's ambitious and brazen attempt to interfere with the 2016 presidential election, the operatives who aided -- wittingly or otherwise -- in that effort, and the extent to which people around Donald Trump lied when faced with tough questions. 1165
