Cops outraged after âBlue Lives Murderâ apparel surfaces on Amazon. Amazon is still hawking âBlue Lives Murderâ merchandise almost a year after similar anti-cop gear first came to light â sparking renewed outrage from the Big Appleâs detectiveâs union, who accused the e-tailer of putting cops âat peril and risk.â In a recent letter, the Detectivesâ Endowment Association demanded Amazon stop selling the âdisgustingâ items emblazoned with the message âBlue Lives Murder.â âIt has come to my attention that your website is selling tee-shirts (sic) and other items emblazoned with the words âBlue Lives Murder,ââ reads part of the letter sent by the DEA to the companyâs Chief Financial Officer Brian Olsavsky and obtained by The Post.
