I like to imagine that Parker has set up an actual Thieves-R-Us store for the Leverage teams around the world where they can pick up sleek black outfits and lock picking sets and anything else they might need for optimized thieving
This, except they are expected to steal it without the staffers (ex-thieves themselves) noticing.
Two or more spottings in a six month period get you pulled in for intensive retraining with Parker...
