Rachel Maddow last night caught up with that strange domestic terrorism case out of Maine that we reported on awhile back as part of a larger trend we're seeing of ratcheted-up rhetoric and increasingly violent expressions coming from the American far right since Barack Obama's election.

Maddow: But should this guy have been found out -- I dunno, before he died? And, post-9/11, have we focused too much on stopping Bin Laden again at the expense of potentially stopping the next Timothy McVeigh?

Good question. And the answer is clearly yes. The Maine incident is only the latest in a long string of cases of serious domestic terrorism emerging from the extremist Right since 9/11. Some of the others include:

-- The anthrax killer.

-- The far-right "Patriot" who constructed a sodium cyanide bomb capable of killing hundreds.

-- The Alabama militiamen who plotted to go on an anti-Latino killing rampage.

-- The ex-Army Ranger who planned an anti-abortion killing spree.

-- The young skinheads who wanted to kill 107 black people and cap it off with Barack Obama.

There has also been outright malfeasance on the part of the FBI when it came to investigating far-right extremists in the past eight years.

That appears to be changing -- the FBI has been public about its concerns regarding the resurgence in white-supremacist hate groups and their activities and recruitment since Obama's election. We'll have to see if that translates into tackling the problem seriously.
