Those who satisfy these demands by citizens are more likely to be voted back into office. It is in their absolute interest to keep their focus on relevant emails or phone talks, as if they don’t do that, there is another person qualified for the job who will.  Secondly, it is clear that in this quest for protecting society, it is in the government’s interest to obey the law. As recent events have proven, the population is allergic to any state agency’s violation of law, especially when it comes to warrantless tapping. They won’t risk breaking the law in the hope they will catch more criminals as they know there would be a society and media backlash. If anything, it is in any politician’s interest to search and investigate if any government agency is conducting such abuses and to reveal it with the resulting plaudits and votes it will bring. A politician will gain much more if it takes a public stance against that agency by imposing tighter controls and inspections rather than secretly supporting it. Let us not forget that it is the people who keep politicians in office.  Thirdly, we must remember that there is a lot of pressure from different NGOs and even whistleblowers that is put on these officials not to make any wrong steps. They know that if the population finds out that they focused on anything else but catching wrong doers, their career is over and there is no coming back.  As a result, we have every reason to believe that the government will maximize its efforts of protecting us, but abusing its powers won’t benefit it on any level.
