John Oliver has been beefing off-and-on with Geraldo Rivera’s mustache for years, and he felt that the time was right to reignite that feud with this week’s Last Week Tonight deep dive into armed police raids. In particular, the host wished to pinpoint the monstrous toll that these raids continue to have in the U.S. (including the horrible instance of cops killing a sleeping Breonna Taylor in her own home); and when Oliver dug back into the history of these raids, which became “supercharged” during the 1980s heyday of the War On Drugs, he noted that Rivera was a key figure in popularizing them.
