This year, LGBT activist and Arizona State student Monica Jones had her November conviction on Prostitution charges overturned on appeal. Jones claimed that she had accepted an offer of a ride home from a Phoenix undercover police officer in May 2013.

She was arrested for “manifesting prostitution,” a statue her attorneys would successfully argue is “unconstitutionally vague.”

Fusion’s Molly Crabapple explained it all here:

So we traveled to Phoenix to meet Jones herself, as well as several others who told us what it’s like to be a trans woman in the desert city. Getting picked up by police officers for simply not conforming to gender stereotypes has led the LGBT community to give a nickname to the alleged crime: “walking while trans.”
