Traders assign a 98.6 percent probability that James Comey will not smile in any mugshot because standard booking procedures produce neutral or somber expressions and Comey has maintained a consistently reserved public demeanor throughout his career in federal law enforcement. Historical examples of high-profile detentions show subjects rarely deviate from protocol under such circumstances. Only an explicit instruction from authorities or an atypical personal decision at the moment of capture could alter the result, neither of which appears likely under present conditions.
