BANGOR, Maine (NEWS CENTER) -- What makes for an effective protest?

Throughout U.S. history, protests have been fundamental to shaping discourse and in some cases public opinion.

A recent protest outside of Senator Susan Collins' Bangor Office that led to some arrests has some people wondering what makes an effective demonstration.

We turned to Husson University Associate Professor of History, David Haus.

He's studied acts of protests throughout U.S. history. Haus says protesting is one of the most American things people can do.

He favors those that are peaceful, mentioning marches and sit-ins during the Civil Rights Era and how effective they were in shaping public opinion and policy change.

"Ultimately it depends on strategy," Haus said.
Haus believes, while it may seem recent protests may not bring change right away, they often spark the conversation that eventually brings about change.
