Is there any estimate for what percentage of chat communication happening within the EU is done by "perpetrators/criminals"? The average crime rate is 40 incidences per 100000 people per year, which would mean 0.0004% of the population is considered a criminal every year. What % of that tiny margin are going to be using online chat to commit their crimes? is it really worth abandoning the privacy of 450mil other people in the hopes that you might stop a criminal?
