Make no mistake, I do live and work in the US. So far I have read the manifesto on my smartphone (iPhone) and one laptop. I saved the pdf for reference on the laptop, so it is backed up in the cloud but not published on the web. This is not against US law. But if I traveled to New Zealand, say in 2022 (this is a possibility) would I be arrested? Will their customs check my private document cloud?
While I was in New York City March 15 I discussed this with an Uber driver and he asked me if I would email it to him. I declined. But it would not have been illegal.
Quartz has a major article by Tripti Lahiri on why New Zealand made mere possession a specific crime. The New Zealand government has an explanation classification document, the QA portion of which is surreal (is if reading the text would infect someone with a virus as in a horror film). But it is reasonable for a country to take exception to the naming of specific places or targets in a document like this. There may be a "problem in Canada", at least in Ontario; I'll check into this story further.
