More difficulty with "as":
1 laws as they existed in the 1900s
2 laws as they relate to public schools
According to standard English, the two sentences mean respectively:
3 laws in the form they existed in in the 1900s
4 laws in the way they relate to public schools
Sentence 3 makes sense, because it means "laws of a certain type". But, I couldn't quite make the same connection with sentence 4. Laws are not action, so using "in the way" with laws seem strange.
