My question involves criminal law for the state of: tennessee - in a felony theft of property case in criminal court, how would paperwork attained off the internet showing that a upc does not apply to only one merchant but to any and all merchants that carry an item, be entered into evidence? Would I need an expert witness to verify this paperwork. I am representing myself in this case due to the fact that I make too much for a court appointed attorney and not enough to pay the $5,000.00 to $10,000.00 that I'm being quoted. I appreciate any help you can give. Thank you.
