At least 2,000 police rallied in downtown Tunis, an epicenter of protest and clashes between youths and police that forced President Zine El Abidine Ben Ali to quit the country he ruled with an iron fist for 23 years.

It was a significant development for this North African country where police who carried out Ben Ali’s policies were widely feared by citizens. The rally took place near the hulking Interior Ministry, a symbol of the dread that Ben Ali’s regime inspired for many Tunisians.

Saturday’s crowd on Avenue Bourguiba, where daily protests have been held, drew many plainclothe and uniformed police with red armbands. They sought to press demands like the creation of a labor union, better pay and — like other protests in recent days — the ousting of any members from Ben Ali’s party from the government.

Officers climbed onto their official cars, blew their whistles and waved flags and signs. Some exchanged hugs to congratulate each other about their chance to protest. Many were joined by their families.

"I am not afraid to come down to the street," said Rida Barreh, 30, who has been an internal security officer for five years. "I work 12 hours a day and yet only get paid 500 dinars ($350, 250 euros) a month."

Barreh said he wanted a labor union to help defend police officers’ interests — and wanted to convince Tunisians in general that "we are here for the people and we want to serve the people."

"The government always made sure the people were scared of us but this must end," he told The Associated Press. "Also I don’t want the blood of our martyrs on my hands."

Added another officer, Nabil Jazeeri: "We need to forget the past and realize there is no home in Tunis that doesn’t have a police officer or a man serving in the army."

For the first time, civilians in the crowd argued openly with some police.

The U.N. human rights chief, Navi Pillay, has estimated more than 100 deaths have occurred during the unrest in Tunisia since mid-December, and is sending an assessment team to the North African country.

Prime Minister Mohamed Ghannouchi, a longtime Ben Ali ally, on Friday pledged to quit politics after elections that are held as soon as possible amid protests by citizens still angry at officials linked to the ousted regime.

Saturday’s demonstration in Tunis came on the second of three days of mourning of dozens who died in the protests that drove Ben Ali from power.
