This is how if a real spy behaved, he would end up in front of the execution squad within a week. Taking pictures of documents in the army office, writing to foreign "enemy" on the ship with a non-involved colleague on board, drawing chalk "smileys" (at that time ???) and crosses on a busy street in front of everyone in the army district ... waste X-th category. And yet such a theme for a really believable spy drama .. :-(
It would take more humility to real heroes.
