Democratic countries are controlled by their voters...
But not necessarily by a majority of the electorate. The price of freedom is eternal vigilance - someone once said... I/we expect our politicians, legislators, police and judiciary to be a bit sharper but, sadly, too many are not and their self interest prevails.
When 'the electorate' stand up and try to be heard (Greece, Middle East, China, Britain ....) they'd better have the 'powers that be' on their side or it will all end in tears.
American Judiciary seems to have more about it when it comes to trying to defend the people against the state but I don't live there so can't comment.
