In 2013, after the death of a colleague whilst on Police duty, the founders of Black Rat Merchandise decided to start a website to support the Traffic Patrol Orphans Gift Fund (a fund that helps provide financial support to the children of Metropolitan Police Traffic Officers that have been killed on duty or extensively injured rendering them unable to work again).
I am not, nor have I ever been, a member of the Metropolotan Police.
