Government works off of law, not merely intentions. Intentions can change. Laws are documented. otherwise what’s the keep of random police officer from deciding that they have the ability to regulate the applications on my phone? After all, they’re just keeping me safe.
Legislation often deliberately leaves interpretation of statutes to the agencies implementing the laws. The legislation can just say "The parks department shall keep the park safe and well-maintained," without specifying what 'safe' means, or how often they collect the trash.
Yes, a functioning government depends on parties acting in good faith and assumes everyone is working for the common good, not always achievable when vast sums of money are in play. This case is a great example.
