All 13, mostly college and Latino, people arrested for sitting down in the middle of the street in front of Alabama's Statehouse Tuesday during a protest of Alabama's tough immigration law have been released from jail Thursday.

Ten were released on $300 bond each Thursday afternoon from the city jail and left out the front door of the Montgomery Police Department chanting "undocumented, unafraid." Attorney Mike Winter says the final two were let out later.

An arrested juvenile was released Tuesday night to her parents.

Those arrested are mostly college students who say they came to the U.S. as children and do not have proof they are here legally.

A spokesman for the federal Immigration and Customs Enforcement said the agency hasn't lodged a detainer against any of the protesters.

The students were among about 100 people, most of them Latino, who chanted slogans as they marched in light rain around the state Capitol and to the adjacent Statehouse where the legislature works.

"Undocumented, unafraid," ''No papers, no fear, immigrants are marching here," and "Ain't no power like the power of the people," were among the slogans the protesters chanted as they marched. Later, some were hauled off to jail in a yellow bus normally used by the city parks and recreation department.

Some sat down on Union Street between the Statehouse and the Capitol when police approached and warned them in English and Spanish that they would be arrested if they didn't move.

Federal courts have blocked parts of the Republican-backed law from taking effect, but both supporters and critics still call it the nation's toughest state law against illegal immigration. The Obama administration opposes the law, which it calls an overreach by the state.

Meanwhile, some of the Republicans who voted for Alabama's new immigration law say they are looking at making changes that they say will make the law easier to understand but won't weaken it.

Republican Sen. Gerald Dial says some mistakes were made in the bill and he's working with other senators to try to address them. 

He doesn't want people renewing their professional licenses or buying car tags to have to prove their legal residency every year. Another Republican senator, Dick Brewbaker, says the documents needed to buy a vehicle and the documents needed to get a tag aren't the same, and they should be.

The bill's House sponsor, Republican Micky Hammon, says he wants to clarify that all military IDs are acceptable forms of legal residency, but he's opposed to major changes.
