Query: How many people are maimed by Chiropractors a year?

I have a few questions to the author. How many people are maimed by chiropractors a year? and What is your definition of scientific? In my chiropractic office I see people hurt and maimed by what I think you would call your "scientifically proven procedure". I invite the doctor to see how many people benefit from the chiropractic care they receive in my office.
