Apparently a man used decoys which he hired on craigslist, and an inner tube, in order to conduct a successful armored car heist.  So for anyone interested in how you would accomplish this feat:

• Post ad on craigslist promising $30/hr for construction work if you show up at a certain place and time dressed in a specific manner: respirator, blue shirt and construction overall.
• Wear clothing matching that description.
• The certain place and time happens to be the time and place of an unloading of an armored truck, mace the man carrying the cash, run.
• Jump in a waiting inner tube a few blocks away, ride it downstream.
• Profit.
