Canadians travelling to U.S. will be photographed upon entry and exit starting Boxing Day

I'm not justifying it, nor am I saying you should visit the States (please don't), but I've been photographed on entry/exit of Japan and NZ the last two years of travelling. Fingerprinted as well in Japan.
I guess I'm just saying that this sadly will become more and more normal globally.
