And barely 24 hours later, it did, with a shooting Wednesday night near the scene of Tuesday's shooting on North Sanborn Road and Del Monte Avenue in East Salinas.
Early reports indicate a police officer attending to the gunshot victim was hit on the head with an object, probably a bottle, by a protestor.
That's when things got really heated, and police responded in riot gear and called in to neighboring cities for mutual aid.
Early reports indicate the officer is receiving medical attention, and the shooting victim died on or near the scene.
Weekly photographer Nic Coury is on the scene reporting live; in the mean time, here are some key updates from social media, which is where the outrage originated.
A viral video showing yesterday's shooting had more than 93,000 views as of 11:15pm tonight. Police asked people to stay calm until they completed an investigation. But word-of-mouth and social media have gotten people riled up fast.
"I need prayers for the City of Salinas, please," City Councilwoman Kimbley Craig posted on Facebook Wednesday night.
Meanwhile, here's a rundown of what's being reported on Twitter from protestors who are in the East Salinas riot tonight:
Protest signs say, "Cops are murderers."
Assisting agencies include Monterey, Marina, Watsonville and Seaside PD, Salinas Valley State Prison law enforcement, and Sheriff's deputies.
"I'm so ashamed to be Latino because of these protesters," one man tweeted.
A small protest began around 1pm, near a small memorial for the man shot and killed yesterday. The group quickly swelled to hundreds.
When a shot was fired after 9pm in the crowded neighborhood, protestors erroneously believed it was another police shooting; there's no suspect yet, according to early reports from the scene.
Disputes on Twitter as to whether tonight's violent protest scene qualifies as a "riot," or a crowded protest.
