hi, i hope you can help me. last year i was charged with possessing a prohibited offensive weapon when a jimmy rigged homemade muzzle break was determined by the police to be a silencer. definately not a silencer, no baffles just a hollow tube. anyway on my way to trial soon and my laywer wants an expert witness. to use his would cost me $10,000 which i definately do not have after paying him 6,000. i have been having an incredibly hard time even getting started trying to find this expert. i am in pittsburgh, pa. "GO STEELERS" if anyone could hepl with some direction about where to find my expert i would greatly appreciate it. thank you all very much. Geoff.
