The ironic thing about people being all concerned about a "income-tax boycott"/non-compliance is that it is now actually illegal to pay your income taxes – the US Code makes it illegal to provide finances to countries engaging in State Sponsored Terrorism, of which Fast & Furious certainly was.
(Fast & Furious was a government operation; moreover, no significant consequences were incurred, by any of: those implementing the operations, those directing the operations, those ordering the operations, and those authorizing the operations.)
Interesting philosophical attempt, but ultimately that would be the Congress/administration that is transgressing the law.
Our responsibility is at a different level. We aren’t policing our body politic for integrity. We have a Constitution. We’d have less problems, possibly a lot less, if we insisted more on integrity TO the Constitution.
