PORTLAND, Maine — Several hundred people protesting the recent deaths of two black men by white police officers in Missouri and New York stopped traffic in the city’s busy downtown on Friday and similar sized group gathered Sunday at another protest hosted in part by the NAACP Portland.

There were no arrests at either protest and Sunday’s “March to End Violence: Solidarity for Racial Justice” which went from Congress Square to Portland High School, “was actually quiet,” a Portland police dispatcher said after the event ended.

“There was roughly 200 people and it took them about an hour to get down to Portland High School where they held a rally,” said Lt. Gary Hutcheson, who was one of six officers who escorted the group.

Sunday’s march was held to allow Mainers “to add their voices to those around the country calling for an end to the proliferation of violence and the need for a justice system that is accessible, fair and transparent for all,” Rachel Talbot Ross, state director of the Maine NAACP, said in an email about the event.

Recent Maine protests have been peaceful, unlike protests in Ferguson, Missouri, where the grand jury declined last month to indict police officer Darren Wilson in the shooting death of an unarmed Michael Brown last summer, and others in New York after the city’s grand jury last week declined to bring charges against police officer Daniel Pantaleo in the chokehold death of Eric Garner, a black 43-year-old father of six.

The Portland rallies and another one held Friday at Bowdoin College mirrored others that took place across the country on Friday and called for an end to police violence, especially against black people.

Portland’s Racial Justice Congress and the University of Southern Maine’s coalition Student Voices of Difference and Unity hosted Friday’s protest march and Sunday’s event was sponsored by the same group, along with Maine NAACP, Southern Maine Workers Center, Code Pink, Veterans for Peace, ACLU of Maine and Peace Action Maine.

Many in the group carried homemade signs that read “Black lives matter.”
