> That's ok but an exception for law enforcement and national security would be useful.
Jesus hell no. Law enforcement already has too many permissions, and you can bet that there are more than enough people who would like the police to put iris scanners, gait monitors and other crap on each train station and public square. Minority Report and Little Brother should be warning enough, I feel no desire to see science fiction becoming reality.
> but IMHO this means we should work on it and see if it can become useful rather than killing it off completely so early by having a blanket ban.
We need a blanket ban because when you grant the government a single digit of your hand, tomorrow it has your whole arm in a vice. "War on terror!" "War on drugs!", "war on prostitution!", "protect our children from kidnapping!!!" - the list of stuff that people will bring up once the technology is in place is endless, and there are enough voters convinceable with fear mongering that the authoritarians will get what they want.
> In any case, individual member states can draw their own laws on this.
Blanket bans and mandatory requirements cannot be overridden, which is part of why many politicians from all EU countries choose the "Brussels backdoor" to pass shit they would get kicked out of office for at home, and when local voters rightfully complain, they just say "complain in Brussel, not my fault, we are just doing the whims of the EU".
(Side note: this despicable behavior and complicit/ignorant media are a major reason for public trust in the EU eroding!)
> On a side note, the wording in English might give the impression that the German government decides EU law...
Let's be real: Germany, France, Italy and Spain are the dominant powers in the European Union. As long as only the Commission has the right to initiate the passing of laws, most initiatives will come out of these "big four" countries, and there will not be any initiatives where it isn't clear from the beginning that they have a high likelihood of passing.
