"Not to put too fine a point on this, but the president has shown he often doesn’t know how to behave himself in public settings. The Boy Scouts, of all organizations, had to apologize for Trump’s antics last week, which came on the heels of a controversial event in which the president tried to recruit active-duty troops into a White House lobbying campaign. This keeps happening. Trump’s remarks at the National Peace Officers’ Memorial Service were obviously inappropriate, as was his speech to graduating cadets at the U.S. Coast Guard Academy. Now it’s police departments nationwide scrambling to make clear they’re not comfortable with the president’s advice on police brutality."
