I think you underestimate how specialized law can be.

I have a relative who is a lawyer and legal attorney who would definitely not know this and when asked would answer that it is not his speciality and that he would have to do more research.

He's an attorney in employment law, and I asked him some things about criminal law and he did not know, and when pressed to make a guess, his guess was wrong.

It seems that law is quite complicated, and that lawyers have their specialities.

Yes and it seems like this would be an even more specialised area. if we don’t even know which lawyer to ask how can we even hope to follow the law meaningfully
