A photographer at the Women's March on Denver, Colorado, was able to capture an incredible moment during the event -- hugs between police officers and protesters.
Bryan Dahlberg, who attended the historic march at its Denver location, said he was shocked when he started seeing people approaching police officers and hugging them.
"About halfway through, I was surprised by an unexpected phenomenon: hundreds and hundreds of people stepping out of the parade to thank the police for being there," Dahlberg told KUSA.
The stunned photographer quickly grabbed his camera and was able to capture one touching moment on film.
"When I saw this group of officers standing with their bicycles, I just waited for the right opportunity. The woman hugged each officer in turn," Dahlberg said.
Across the world, more than one million people collectively marched in protest of President Donald Trump and his controversial stances and statements.
"There were a lot of messages," 36-year-old Dana Gwinn, who traveled from the Bay Area in California to Washington, D.C., to take part in the main march, told NBC News.
"I felt today like I felt on election night. I want to be mad about 15 different things, and everyone says you need to choose what your battle is going to be and stick to that one thing. But I don't know anyone willing to choose."
In contrast to the anti-Trump protests on inauguration day, the Women's March on Denver did not result in any arrests. The inauguration protests, however, saw 230 people being arrested for looting and other crimes. Some arrests came from an incident in which a limo was set on fire.
"This is not about people doing stupid stuff and getting arrested," Maryland resident and D.C. marcher Robin Gilmore said of the anti-violence approach to the women's march. "Really, the police are cooperating. This couldn't happen without police cooperation."
Marches took place all across the world -- most notably in cities like New York, with 400,000 attendees, Chicago with 100,000, and Atlanta with 60,000.
