Traders assign a 98.6% implied probability against former FBI Director James Comey smiling in any mugshot, driven by established federal booking protocols that instruct subjects to maintain neutral expressions during processing and by the professional conduct typical of high-profile officials in legal settings. This near-certain consensus reflects consistent historical patterns in which public figures avoid expressions that could be interpreted as minimizing the seriousness of charges. Key influences include institutional procedures at U.S. detention facilities and Comey's record of emphasizing adherence to legal standards. While the market views alteration as unlikely, realistic scenarios that could shift the outcome include revised booking guidelines at federal agencies or an unanticipated arrest where Comey deviates from standard instructions.
