Mark Slaughter is very rude, I asked him to check the body camera of my stepfather arresting officer and to also check the fingerprints on the dagger they are charging my stepfather with, because my stepfather believes the knife was planting on him and Mark Slaughter told me "I am not taking any tips or leads from someone inside a mental hospital" I told him the tip is coming from me and I am fully competent and he asked me repetitively "Is there anything else I can help you with" I asked for his state bar # and he hung up in my face.
