Fun fact: ~80% of Singaporeans live in public housing and all the entryways to those buildings are filled with (offical) police security cameras, including two in each lift. The cameras extends to the nearby carparks, carpark gantry (to ID the driver), bus stops (and on the bus) so all movement can be monitored. Private housing do not have such police security cameras because the estate is gated and have their own security guards, not that crime is much of an issue there. Dystopia for the masses?
