> In both cases, she used sophisticated tradecraft that sought to leave no trace in databases accessible to European authorities. For instance, she booked her trips and bought her plane tickets using her Czech passport, registering only that nationality with the Greek airline. But upon crossing the Russian border, Šapošnikova used her secret Russian passport, thus bypassing the need to obtain a Russian visa issued to her as a Czech citizen and eliding the digital footprint associated with the relevant application.
“ sophisticated tradecraft “ lol what?
It’s generally illegal in most countries to use another country’s passport within the country your passport is from. You can’t have a German and Argentinian passport and enter Germany with the German passport and leave with the Argentinian one. Nor can you leave Germany with just the Argentinian one. You can go to other Schengen countries, but you can't leave the Schengen region ("since is your entrance stamp?")
