So cite which documents support the claim. If it’s so easy it shouldn’t be hard to do. You’re basically replying to a statement of that’s illegal and being asked to cite what is illegal by saying reference all of the legal caselaw. It may be technically correct but it’s useless. There is a reason academics and legal scholars say reference paragraph x of book y etc. if you can’t provide easy examples why would I buy your claim?

Put up or shut up.
