Don't forget the fastest way to lose rights, by getting the public to think that it is their idea and voluntarily surrender them.
Those in power always use the same trick to erode basic human rights, "Public Saftey superceeds civil rights". If you can really scare the general public enough, you can pretty much do what ever you want to them. They will run happily towards tyranny if they think it will give them a little temporary saftey.
It's history that seems to repeat itself over and over. Do some research on Sparticus and Marcus Licineus Crassus. A Roman citizen that went from a fire fighter to wealthy land owner to Rome's first all powerful god-emperor-caesar, simply by allowing Sparticus and his gladiators to rape, kill and rampage up and down Rome for a few months.
