There's a big mobster war going on in Serbia (and region) right now, and almost all of the dozens of recent big murder cases were at least partially solved thanks to surveillance cameras, phone tapping and cell towers logs. So surveillance when used for good can be extremely useful tool for justice and increase the safety of the public.

It's the same mentality as with the nuclear plants paranoia. Yes they can be dangerous if protocols fail, and yes that makes them a liability and requires constant care - but it's not a reason to completely ban a technology which also can give so many benefits to the society.
