Most of what you just said was entirely wrong. But thanks to someone else telling me I was wrong, I already have the page pulled up. From the ADA website

"Q5. Does the ADA require service animals to be professionally trained?

A. No. People with disabilities have the right to train the dog themselves and are not required to use a professional service dog training program.

Q8. Do service animals have to wear a vest or patch or special harness identifying them as service animals?

A. No. The ADA does not require service animals to wear a vest, ID tag, or specific harness.

Q17. Does the ADA require that service animals be certified as service animals?

A. No. Covered entities may not require documentation, such as proof that the animal has been certified, trained, or licensed as a service animal, as a condition for entry.

There are individuals and organizations that sell service animal certification or registration documents online. These documents do not convey any rights under the ADA and the Department of Justice does not recognize them as proof that the dog is a service animal."

I agree, people skirt the law. That is literally my point. The law is nearly unenforceable because protecting the rights of disabled people is the more important issue. I'd rather have solid protection for disabled people's rights, even if that means people abuse that protection to beat other laws.
