Earlier quoted context omitted.
On the flipside e.g. in Germany this has been used to track down creators of illegal graffiti, using a law that is intended for terrorism and other heavy crimes. We can allow search and rescue missions without having to also accept abuse of power.
Can you reference anywhere where that happened because I've never heard of that and would expect huge pushback in Europe in general..
A very short summary: the law is only supposed to be used for very severe crimes and only if the investigation would otherwise be significantly more difficult or impossible. Also the owners of the tracked phones have to be notified of the tracking as it is a violation of the person's rights. In reality (at the date of the talk) it had never been used for terrorism, about 5% of the time for crimes like murder and in over 70% of the time for theft (including a case of stolen empty beer barrels), and nobody was ever notified.
