I agree that the criminal justice system is flawed, and injustices are far more common than is realised or admitted. I also agree with your observation that the system is loaded against particular sections of society: black youths, the working classes and the unemployed, abused women and so on. This has been illustrated in this very thread, where whole sections of society have been labelled "trash" and "yobs" (instinctively, I believe, not maliciously) for which the harshest penalties must be used to punish their crimes.
Murder is not a black or working class crime. It is certainly not a female crime. While more murders occur among the lower classes, they are usually committed in the heat of the moment, whereas, when a killing takes place among the higher social classes, power or money is usually the motive. It might be cynical of me, but I suggest that working class killers use murder where they see no other option, or where they lose control, while upper class killers see murder as the most expedient way to achieve their purposes, after calculating the pro's and con's and concluding that a person's death is necessary. Such people would never be called yobs or trash.
I have no doubt at all that his toys would be used to smear your character and to suggest this is indicative of your guilt (and possibly implicate him too).
