From the Stasi article on Wikipedia:
By 1995, some 174,000 inoffizielle Mitarbeiter (IMs) Stasi informants had been identified, almost 2.5% of East Germany's population between the ages of 18 and 60.[12] 10,000 IMs were under 18 years of age.[12] From the volume of material destroyed in the final days of the regime, the office of the Federal Commissioner for the Stasi Records (BStU) believes that there could have been as many as 500,000 informers.[12] A former Stasi colonel who served in the counterintelligence directorate estimated that the figure could be as high as 2 million if occasional informants were included. - https://en.wikipedia.org/wiki/Stasi
According to this[1] there are 1.22 million police in the US, which is about 0.373% of the population. Imagine 10 times as many police / informants / analysts / etc.
