Outrage was expressed by people across the country Thursday after the separate killings of two more black men in altercations with police, both chronicled in cellphone video. NY1's Dean Meminger filed the following report.

A disturbing video from Minnesota: Philando Castile shot dead Wednesday by an officer.

The night before in Baton Rouge, Louisiana, Alton Sterling was killed by police.

President Barack Obama says these tragedies are playing out far too often across the country.

"There's a big chunk of our fellow citizenry that feels as if because of the color of their skin, they are not being treated the same, and that hurts," Obama said.

Philando Castile's girlfriend immediately made that point known, going on Facebook live immediately after he was shot by an officer so her family and friends could see what was happening in real time. She tried to stay calm as she spoke to the cop and her audience.

Minnesota Governor Mark Dayton said racism played a role in the shooting and that the Justice Department will assist in the investigation.

"Would this had happened if those passengers, the driver and passenger, were white? I don't think it would have," Dayton said. "I can't say how shocked I am and how deeply, deeply offended that I am that this would occur in Minnesota to someone who was pulled over for a taillight."

That shooting occurred as protests roiled Baton Rouge, Louisiana following the killing of Alton Sterling.

Officers struggled with Sterling while trying to arrest him. They said he had a gun in his pocket, but his familiy's lawyer says police should have defused the situation.

"He's not fighting, he's not throwing punches, he is not stepping forward to the officers. he is standing there. But yet you see one of the officers do some kind of  WWE tackle," said Sterling family attorney L. Chris Stewart.

Obama says the movement Black Lives Matter doesn't mean Blue Lives don't matter. He says all Americans must come togethe to stop tragedies like these from happening."
