In Hungary, Csongor had had very little access to guns. But on a trip to a hacker conference in Vegas two years ago, he had spent a couple of evenings at firing ranges that catered to foreign visitors, and he had learned a few basics. He figured out how to eject the clip from this weapon, then maneuvered it into a shaft of sun coming in through the crack in the roof and pulled back the slide just enough to verify that no rounds were in the chamber. Then he found the safety and flicked it back and forth a couple of times just to get a feel for when it was on and when it was off. When he was certain that the weapon contained no cartridges and that it was inert, he set it on the van’s seat next to him, then reached back into the bag pocket to see what other treasures might be contained in there. He came up with a spare clip for the pistol, fully stuffed with cartridges. Then he pulled out a pair of heavy black cylinders with steel rings affixed to their tops.
