In Greece after the Dec 2008 uprising and during the pseudo-fiscal-crisis that begun shortly after, there was an anti-terror law that included wearing a mask or covering facial characteristics in public. Luckily for them, during an alliance gov. of far-right-nationalists with some opportunist sociodemocrats in 2016-19, they banned this law before #Covid appeared. In 2020 they tried to ban demonstrations and protests in open space to "protect the public".
