Public Awareness, Street Cred and Notoriety are just weird. Let's say you're a cautious, professional runner. You do some jobs, you get some karma, your Street Cred goes up. Cool. Now, as it goes up, your Public Awareness starts going up. Pretty soon, the cops are going to have a file on you because your Public Awareness is getting too high. You need to buy down your Street Cred so you need the Notoriety, so you have to start doing crazy, irresponsible things just so the cops won't know who you are. Any system where you're throwing the mayor under a bus on live 3v just so the cops will know less about you is working on some pretty strange assumptions.
And yeah, you can Rule Zero it (and should, early and often), but that doesn't make it any less weird.
