Live Stream: 'Free Speech' rally under way in Boston, Mayor to protesters: 'stay away'

Watch live as demonstrators hold a 'free speech' rally in Boston. Counter-protests have also announced they will attend. Local authorities say they are determined to avoid a Charlottesville-type confrontation between thousands of conservative and libertarian activists. Mayor Marty Walsh has said he prefers protesters simply stay away.

On Friday, Police Commissioner William Evans said 500 officers would be on hand to keep the two groups apart.
