Why is ignorance of age not an excuse?

It looked to me like you were drawing a distintion between ID cards and other forms of documentation. I already said ID cards are unreliable, so don’t rely in them.

The photographs were no persuasive to me. The children in those photos all clearly looked like children to me.

I fail to see your point here. Anecdotal evdience about people borrowing other people’s ID? So what? those ID photos did noty look like the people who were borrowing them.

Where does the government come from and who writes the law?
