Abuse of power by police forces (or certain individuals in police forces) has been a problem for a long, long time in just about every society I know of. It's not a problem that can ever afford to go ignored. I've witnessed it firsthand myself back in the 70s. What is most disturbing is when a supposedly responsible civil government, in the name of "national security" starts legislating away the constitutionally enshrined civil rights of its citizens. Then it is time for that government to clean up its act fast or get tossed out of office.
