A Massachusetts man who allegedly placed an advertisement on Craigslist inviting would-be cop killers for drinks was taken into custody by Cambridge police, according to Newsweek.

"Sick of Somerville and Cambridge cops who live in Sudbury or some other f--- place? Let’s kill them," the Craigslist post said.

"I want to see people killing cops and Uber drivers in and around Cambridge and Somerville and I'll buy you a drink," the advertisement said.

James Seawell was booked and charged with soliciting and threatening to commit a crime.
