Two police officers in Buffalo, New York, have been suspended without pay after they were caught on camera shoving a 75-year-old protester, causing him to fall and knock his head to the ground. Gov. Andrew Cuomo said Friday the local district attorney should investigate the case for potential criminal charges.

Barring that, the governor thinks the officers should be fired. Cuomo said he had spoken with the injured protester and said the graphic video of the encounter made him "sick to my stomach."

"It's just fundamentally offensive and frightening," Cuomo said. "Who are we? How did we get to this place."

The confrontation occurred shortly after the city's 8 p.m. curfew on Thursday, NBC affiliate WGRZ reported. Journalists from Spectrum News Buffalo and WBFO were reporting in Niagara Square as they witnessed officers lining up to push back protesters who were out calling for police accountability and racial justice following the death of George Floyd. One of their videos shows the elderly man calmly approaching the officers, appearing to ask them a question, but the officers pushed the man back.
