Giving up fingerprints is a major issue imo though, these cannot easily be changed ever, if you lose your password, fine - then change it - but you cannot easily change your fingerprints. Unless it's completely mandatory, like entering the US on a flight, I see no reason to ever give away your fingerprint. Heck, I don't even understand why people accept to do this on iphones.
Ich habe noch nie USA Territorium betreten und werde auch in Zukunft gerne darauf verzichten (inkl. Fingerprints). Wenn die EU so weiter macht (TTIP, usw), ist es sowieso nur eine Frage der Zeit, bis die USA hier 28 neue Staaten annektiert.
There was a UK couple tweeting after landing: "Going to destroy Las Vegas" as in 'going to have a great party time'. They were put on the first plane back to the UK..
