I understand where you're coming from, but you also have to take into account the history of all of Germany. Her citizens were led into one of the worst atrocities of modern times - the mass genocide of millions of Jews. These crimes were perpetrated by ordinary people like you and I. The German law recognizes this conundrum and that murderers, while they may have done horrible things, were seduced by poor thinking. While I would agree that some murderers are self deprecating to the point where they will continue to have poor thinking. As evidenced by German society as a whole, these same people who were once murders can come to a point of recognition of the atrocity of their actions, and learn to find healthy ways to relate when problems arise. I have met with a number of Germans who, while not old enough at the time to have committed the atrocities, were old enough to remember what it was like, and all of them not only express shame in what happened, but also a need to distance themselves from the mindsets, even those they were participatory in. People who express remorse and distance themselves from a murderous mindset show the ability of people to change.

By claiming that you shouldn't need a license to practice these types of claims, MediaSentry has essentially decided that any simple google search of a user should suffice as verifiable evidence. The reason the law was created, and the reason that the law exists is to make sure that the supposed evidence is actually legitimate. A private investigator is likely to do a real search into the evidence to see if it is legitamate, whereas a simple google search leaves no proof, but merely a statement of possibility. If someone were trying to deceive people who were spying on them, they might use a false IP address, and thereby throw off the untrained. This is why governments require a PI license, and why these ready, shoot, aim lawsuits aren't legally sanctioned. It's based on the idea that most of the time they'll get it right, not proof that they're right first.
