Now look, I am the first peron to be against any coverts surveillance, but I don't see what is the deal here.

I mean, if you want to travel, you need to have a passport, for which you have to give up your biometric data as well as take a picture for it.

So this, I understand, is only somekind of security check to see if the person using the passport matches the passport.

I don't see the big deal with taking 2 pictures instead of one.
