Not only that but he manufactures and sells lock picking equipment and consults on physical security. There's nothing part time about LPL's lock picking any more.
Well, we don't know what his main job is, only that he lives in Washington DC. I would assume because of his location that he works for the US government, and that this is the reason he does not want his face on video.
whether he does it as a side job isn't really relevant, but I do think that there's a bit of a cult of personality going on here.
he's clearly a good lockpick, but even in a thread that isn't about him, he's somehow dominating conversation and gathering plaudits. I completely agree that being famous doesn't make you the ultimate arbiter of anything
