Chiropractors (quacks or legitimate doctors?)

[FartinMowler]

One of my snowplowing contracts is a Chiropractic office. One day I went in to talk to the "Doctor" who runs it and I noticed some parents taking a small child ( age 3-5) into one of the rooms. I was kept waiting and having a conversation with the receptionist and and subtly asked "why would a small child need a Chiropractor?" The receptionist said that a lot of people bring there kids in for "adjustments" and it was very safe. Being a parent and never having gone to a Chiropractor I did a search on the net and found a gammut of info about people having siezures and dieing.

Do you think this is a legitimate health profession? and should they be allowed to "adjust small childrens spines"?
