HUNTSVILLE, Alabama -- Opponents of Alabama's new immigration law are planning a protest march through downtown Huntsville on Saturday.

Molly Carrizales, co-organizer of the event, said the march will start at 1 p.m. in the gravel lot across from the Clinton Avenue post office and wrap around the courthouse square, ending at Big Spring International Park.

The group got a permit from the city this week and will have a police escort, Carrizales said.

"We're going to keep fighting to change this inhumane law," she said today. "For those that don't approve, we'd like them to be respectful. We don't want any negativity."

Carrizales said her father entered the country illegally from Mexico in the 1960s but later became a U.S. citizen.

March organizers have posted fliers in neighborhoods and apartment complexes across Huntsville to raise awareness about Saturday's event. Carrizales is hoping for a crowd of at least 200.

"It's kind of up in the air," she said. "A lot of (illegal immigrants) are still afraid to come out."
