The reason I asked for a JB cite was because we actually know very little about just what happened when it all hit the fan back then with Justin, Elaine, and Harry. Harry revealed a little bit of it when he told that story to Lea back in Ghost Story, but we still don't know much.
We don't even know for sure if Harry actually broke the First Law or not in that fight. Even Harry doesn't seem to recall all the details, even he might not be certain. Or at least, nothing I've seen reveals anything much.
We also don't know much in detail about how Harry met Bob or just what Harry did after that fight was over. I don't know that we even know how long it took for the Council to track Harry down after it all went down, or when they found out he existed, or what.
