Chicago police have launched an internal investigation into a series of incendiary posts by a person claiming to be an officer in an online forum regarded as one of the darkest corners of the web.
Many of the posts on 4chan’s /pol/ board are racist and homophobic. They include photos of Chicago police uniforms, a city-issued ID badge and a gun — all covered by post-it notes with the forum’s name and a date written on them.
