An activist group has tried to jam the chief of the Madison Police Department's phone line with calls demanding the termination of a police officer.

Freedom, Inc.'s Bianca Gomez says at least 100 people Wednesday placed phone calls to Chief Shon Barnes and urged his firing of Officer Matt Kenny, who fatally shot Tony Robinson, in 2015.

Kenny was deemed to have been justified in his use of deadly force and while removed from patrol duty, received no workplace reprimand.

Barnes declined to comment Wednesday on what Freedom, Inc. called its phone jam. But earlier this year, Barnes told 27 News there would be no revisit of Kenny's job status unless new information surfaced.

Activists maintain Kenny was untruthful about his encounter with Robinson. Kenny and Robinson came upon each other in an apartment stairwell, and Kenny says Robinson attacked him before Kenny shot him. Records show police responded to the location after Robinson was reported to have been acting erratically, running into traffic and assaulting a bystander.
