It's just like being a spy in the US
You can break the law in the USA if you work for certain areas of the US Gov't.
For instance, you can sell weapons to Mexican drug cartels (even when they will be used to kill US citizens), not follow the law on recording and retention of government documents, lie to the American people about what really happened in Bengazi to name several.
Let's not forget the latest items. Such as overturn an election for POTUS, lie to the FISA court, leak confidential information to the press, etc.
If you want to break any law, get elected to the US House of Representatives. You don't even have to worry about the separation of powers clause, or the court system. You can even outright lie to the public, and say anything at all on the floor or committees of the House!
