It's not an exaggeration. You're assuming that current authorities are interested in and have the capabilities to prevent the criminals and traceable crimes you speak of and that there is an ongoing, massive effort to do so. For most crimes, this isn't currently the case, at least in the US, even though the data is being collected. Right now, only high profile cases get this treatment (think Boston marathon bombing) and there is generally no problem solving those. It could be the case that this starts to be applied for victimless petty crimes (the favorite here in the US to lock up people on) and thought crimes soon as it was in the Soviet bloc countries. I wouldn't be surprised as this stupid idea that all infractions of criminal code (formerly called crimes, but that implies malicious conduct which is not the case for most infractions in the US) can be solved and should be punished is pretty popular in the US (tough on crime attitudes), despite ignoring the fact that almost all major positive social change comes from criminals (civil rights movement, gay rights movement, cannabis legalization, etc.). I'd like to say that the police in the US do not have the same nature and motivations as their communist equivalents, but the only real difference is the size of the population and those pesky bill of rights amendments. So really, for practical purposes, only the size of the population.
