It is obvious that warrantless tracking of citizens is not the only way to fight crime. There are other ways which do not negatively impact the citizens to such an extent.  When talking exclusively about protection, the government could have better trained police officers, harsher laws in other to deter criminals from committing infractions, improved gun control regulations and a more efficient judicial system. There a lot of alternatives to this, as the elected officials must understand that they need to choose a path which does not hurt the population.  Moreover, if we look at statistics (1), in most of the western world, the crime rate has been decreasing. Slowly but surely, crimes are falling and our societies are becoming safer and safer. Thus, not only we have other ways of fighting crime, but crime is becoming less of a problem, so do we really need new intrusive measures to deal with it?  (1) Eurostat Statistics,
