A friend went through an ordeal a few months ago. Cops came to his apartment under the guise that they had been tipped that a dangerous criminal was living with him and that the room also doubled up as a 'drug shop'. When my friend denied even having the knowledge of the said criminal and that he had never used drugs all his life, they simple cuffed him and placed a pistol in his hands and also a packet of marijuana then escorted him to the station. He went to court, and due to lack of enough proof my friend was released. What does one do when confronted with an ugly situation like this?
