As a licensed acupuncturist,I had to be in a supervised clinic setting for 3 years before I was allowed to independently needle people. There is not enough clean needle technique training in dry needling programs. I had to take a written and practical exam. Why hold my profession to these safety standards and not hold everyone that needles the public to the same.  Trainers have even less schooling in anatomy and physiology than physical therapist. A long weekend course is never going to be enough training to deal with serious life threatening possibility of dealing with blood and piercing into tissues.
