Yes, I think that these to medical conditions are about the same in what they do to the body, and how they harm you. I think that it would be ok to classify them as the same level on the disability ratings, since they are very similar in what they do.
The reason for this is because some cases of spinal subluxation result in the same disabilities as being paralyzed does. It's a disorder of the spine and can cause you to not be able to function at all. When you have an impairment that disables you as much as paraplegia, you should get the same benefits.
Even in this day and age, it is hard to be sure that you've identified the actual criminal. In cases where the criminal is properly identified, they are obviously mentally ill if they murdered people. Therefore, I believe there should be some forgiveness. I don't believe they should have luxuries though, and they should have to work to support themselves financially. They should also have access to professional help.
Spinal sublaxation should not be categorized as a disability functionally equivalent to paraplegia. Doctors and Chiropractors disagree on what the term sublaxation in the spinal chord refers to. For doctors a sublaxation can refer to any an all malfunctions in a certain part of the spine, while Chiropractors contend that slight malfunctions in the spine are considered malfunctions just as much as large ones.
No, spinal subluxation should be categorized as a disability functionally equivalent to paraplegia, because one is much more severe than the other. Each person has physical disabilities and challenges that make them different than other people, but they can not all be classified as disabilities. Subluxation is not as bad a paraplegia.
