Law abiding citizen.
I am governed by tens of thousands of pages of laws at three1 (four?2 five?3) levels of government. These laws have been interpreted and reinterpreted many times by tens of thousands of court cases. I am legally obligated to follow every one of these laws.
Actually, I don't need to follow these law and their most recent court interpretations. I need to follow whatever future interpretation is made by a prosecutor and accepted as correct by the presiding judge when my case is being argued. (And they say no post ex facto laws.)
I've broken several today. I'll probably break more by day's end.
1 Federal, State, and County.
2 Federal, State, County, and Town. I'm not in the town limits, but they have some territorial jurisdiction, preventing--for example--us from building a new shed.
3 Federal, State, County, Town, and International. Maybe I'm only under international law because I'm under the Federal law that inherits international law.
