California city braces for planned anti-Islamic law protest

ROSEVILLE, Calif. -- What's being called a nationwide day of action against Muslims is expected to unfold across the country on Saturday, CBS Sacramento reports. 

In Roseville, "Act for America" -- a conservative, right-wing group that is known for spreading anti-Islamic messages -- has planned a march.

The rally is expected to take place at the Fountains Shopping Center, but it's being met with opposition by another group.

Members of "Roseville Resistance" -- a left-wing, grassroots group -- say they plan to counter-protest in a unity rally. 

Protests and counter-protests like these have turned viciously violent in years prior. In 2016, at the state Capitol, a massive riot broke out as alt-right and anti-fascist groups clashed. Ten people were stabbed and others injured.

In April, more violence erupted at a Berkeley protest when a woman was punched in the face by a self-proclaimed white nationalist. 

According to Facebook event pages, members from anti-fascist group Antifa and the Bay Area Alt Right Movement, who have both been involved in violent protests before, plan to attend Saturday's gatherings.  

Roseville Police say they're prepared should things go south.

"We're making plans for a number of different scenarios," said Roseville Police Department Public Information Officer Dee Dee Gunther. "Of course, we're just hoping that people will express themselves peacefully and go home." 

CBS Sacramento reached out to Act of America headquarters in Virginia, but have not received a call back yet.
