I always wonder how many idiots have been denied entry because they were dumb enough/drunk enough to think it'd be fun to tick the wrong box on that form.
I also love how under the Paperwork Reduction Act they have had to estimate the burden of filling it out, but seemingly not consider whether or not is serves any actual purpose to ask those questions in the first place.
Moreover the form do not specifically mention concentration camp guards:
> "(...) between 1933 and 1945 were involved, in
any way, in persecutions associated with Nazi Germany or its allies?"
I guess Wernher von Braun, like most of the people included in the "Operation Paperclip" would have fallen in that category in some way.
The poor grammar is vanishingly unlikely to be unintentional, considering how many reprintings these forms must have undergone.
