Buffalo police officers suspended after shoving elderly man

• The man is in serious but stable condition, and suffered a concussion and lacerations.
• Police Capt. Jeff Rinaldo said that an internal affairs investigation was opened.

Why it matters: Police across the country have faced backlash for their response to peaceful protesters, including their use of rubber bullets, tear gas and the use of excessive force.

What they're saying: Buffalo Mayor Byron Brown said he was "deeply disturbed by the video" and found it "disheartening" after days of mostly peaceful protests in the city.

• New York Gov. Andrew Cuomo tweeted that the incident was "wholly unjustified and utterly disgraceful."
