There were also frequent reports that police sometimes harassed or detained men with beards whom the Government suspected because of their "Islamic" appearance. After the revolution The fall of the Ben Ali regime has loosened religion repression and brought more religious conservatism, and sometimes more extremism. The 1988 law banning non-state approved activities and meetings at mosques was discontinued allowing much longer hours of operation.
