Yukari Mihamae, a 61-year-old woman from Colorado, was arrested at Phoenix Sky Harbor International Airport after she allegedly grabbed and twisted the breast of a female Transportation Security Administration agent during a screening — an act that she subsequently described not as assault but as protest against what she characterized as invasive and degrading security procedures.

The case became a flash point for the ongoing and deeply polarized debate about airport security in the United States. On one side, critics of TSA's enhanced pat-down procedures — which were introduced after the 2009 underwear bomber incident and expanded in 2010 — argued that Mihamae represented a kind of popular frustration with security theater that had crossed a legitimate dignity line. Online, she found vocal supporters who framed her actions as resistance.

On the other side, law enforcement officials and many commentators argued that whatever one thinks of TSA procedures, physically assaulting a security agent is not a form of protest that a society can excuse. The TSA agent was doing her job. The remedy for objectionable security policy is legal and political challenge, not physical attack on the individuals implementing it.

The broader context is a TSA that had spent years navigating the impossible politics of airport security — condemned for invasiveness when it expanded screening and condemned for negligence whenever a security failure occurred. Its pat-down procedures generated the most visceral public reaction, particularly when applied to elderly passengers, children, and individuals with medical conditions.

Mihamae was charged with felony sexual abuse. The case did not produce the policy change her supporters hoped for, but it did add to the accumulating pressure that eventually led TSA to modify its procedures.
