A year ago Russia jailed Evan Gershkovich for doing journalism. He’s still there | Margaret Sullivan

The 32-year-old Wall Street Journal reporter's imprisonment is a gross injustice and an affront to press freedom

The photograph, framed and in a place of honor, is precious to me. Taken in 2016 outside a Manhattan restaurant, it's a casual shot of four young people and me, everyone smiling. I was concluding my stint as New York Times public editor, and each of these talented young journalists - plus one more who couldn't make it to the dinner - had served as my editorial assistant at some point over a four-year period.

Almost eight years later, I've kept tabs on them. Two still work at the Times, having climbed the newsroom ladder to become a courts reporter and a book-review editor, respectively. One recently has experienced the joy of his first child's birth. Another has bought a house, with her husband, after moving to Seattle.
