My reasoning is that I feel that politicians are constantly filling with existing laws and the changes are conveyed via strang legal terms, e.g. "This changes "they to us in paragraph five, section 2, line 3". This is a complete bullshit way of informing the public about the changes to our laws. If laws where tracked the same way we as developers track our code, hiding even minor changes would be impossible. Just imagine getting a daily / weekly change log for the laws passed by your government. Even our lazy journalists should be able to dig up something in appropriate every now and then if they knew what changed.
Wonderful idea.
