The Milwaukee Board of Aldermen is considering a plan to terminate at least two contracts with American Sewer Services.  That city contractor could lose millions in response to posted pictures of its employees carrying guns at a worksite and a K-K-K sticker on a food cooler.  Some of the work has already been completed, making it difficult to terminate the agreements.  Emotions were high as two south-side aldermen said the sanctions being proposed were too hard on a company with 30 years of “stellar service.”  Another alderman says the facts show the company clearly tolerated racism.
