Just after 6:30 p.m., the crowd quickly grew to about 500 demonstrators, all with the same message.
"It's time. It's long over due. We're just tired of seeing this brutality and no justice. We need justice," said marcher N'Neka Gaines.
Many held signs that read "Black Lives Matter," marching along with chants like, "I can't breathe" and "Hands up, don't shoot."
This is the same tune as the thousands of protests not only here in Arizona, but throughout the country.
On the way to the police department, businesses opened their lobbys to protesters who need water, restrooms or a place to sit and charge their devices.
Several businesses set out water for protesters marching along main street showing their support to the movement.
No word yet if another demonstration is being held in Mesa Wednesday.
