The Black Lives Matter movement that's arisen in response to police shootings of black men is part of a long line of protest movements that have transformed America for the better, President Obama said Sunday, defending the protests amid renewed tensions over race and policing across the country.

At least 48 people were arrested Sunday in Baton Rouge, local media said, hours after Sheriff Sid Gautreaux said that 102 protesters had been arrested in late Saturday demonstrations. "We're here saying 'Hey, can we talk to somebody and see if we can get on the same page?'"

The Washington Post database on fatal police shootings found that twice as many white people (49 percent) were killed by police officers than black people (24 percent) in the first half of 2016. But the two men disagree on whether the Black Lives Matter movement - a nationwide effort to bring attention to the deaths of people of color at the hands of police - is a force for good or causes harm to police. Unfortunately, the same can not be said of the response of the various police departments involved in these shootings whose immediate response is to protect their officers rather than to obtain justice for the victims.

Baton Rouge Police Chief Carl Dabadie Jr., at a press conference Sunday to explain the arrests, acknowledged a Baton Rouge officer pointed an assault weapon at protesters, but he said a supervisor immediately intervened to secure the weapon from her. "Black lives matter. White lives matter". And I also understand why people in the black community are sometimes afraid of police officers when they shouldn't be afraid of police officers, they should seek their help.

"I don't think that we can hold well-meaning activists who are doing the right thing, peacefully protesting, responsible for everything that is uttered at a protest". A counter-protest formed across the street.

"Get the f... out of here", the lead organizer frantically chanted into the face of the stunned reporter, who politely defended himself by saying, "I asked you..." "Black Lives Matter is a peace movement".

"People are against the feeling that something could happen to me and no one is punished".

On Thursday evening Micah Johnson, 25, opened fire on police officers monitoring a Black Lives Matter protest in Dallas, Texas, killing five and injuring seven more.
