A forensic scientist I am not. However, the following comment to M. Simon's post about the suicide of Michael Scott intrigued me:

Was Scott left-handed?

I found a fascinating three-part YouTube video showing Michael Scott (with Congressman Danny Davis, our current Secretary of Education Arne Duncan, and State Senator Rickey Hendon) at an allegedly illegal meeting held at Edna's Restaurant in Chicago, and he does seem to favor his left hand. In Parts 1 and 2, he holds his coffee cup mostly with his left hand (even though there is someone sitting to his left), and in Part 3 he drives away after pausing to insult and scold the photographer -- at whom he repeatedly points remonstratively and shakes the index finger of his left hand. (Scott is sitting all the way at the back of the table, wearing a white baseball cap.)

By the way, these videos provide an interesting behind-the-scenes look not only at Michael Scott, but at the inside world of Chicago politics -- especially as it pertains to education. A more detailed explanation of the nature of the secret meeting is provided here.

Considering who some of the participants are, they arguably provide a behind-the-scenes look at the inside world of the people who are now governing the country.

A few brief Wiki excerpts about the "Breakfast at Edna's" participants.

An October 9, 2008 story in The Washington Post told of substantial tension between Hendon and then colleague Barack Obama, culminating in a physical confrontation in June 2008. Nonetheless, Hendon supported Obama in the 2008 presidential election.

Although Davis was fully promoted as a Democratic candidate, he also ran as a New Party candidate.[16][17][18] Supporting this was New Party's celebration of him as the "first New Party member elected to the U.S. Congress."[19] Although the State of Illinois did not permit fusion voting, New Party advocated fusion voting as a means to promote their party and party agenda and to particularly project New Party ideology into the mainstream Democratic Party.[20] Candidates were referred to as "N[ew]P[arty] Democrats"[20] and were required to sign a contract mandating a "visible and active relationship" with New Party.[21] During this timeframe, New Party was experiencing substantial growth[22] and included in its ranks a young Barack Obama.[16][17][21][23]

[...]

Davis expressed interest in being President Barack Obama's replacement in the U.S. Senate, and Illinois Governor Rod Blagojevich, who was expected to appoint Obama's successor in late 2008 before his own major scandal erupted, stated that Davis would "make a great senator."[31] In a December 31, 2008 article published on the website of The New York Times, Davis said that he turned down an offer from representatives of Blagojevich to appoint him to the Senate.[32] Instead, Blagojevich appointed Roland W. Burris.[33]

Duncan has extensive experience in educational policy and management, and he was a teacher from 1990 to 1992. In 1992, Duncan became director of the Ariel Education Initiative, a program to enhance educational opportunities for children on Chicago's South Side that was started by John W. Rogers, Jr.. In 1996, along with Rogers, he was part of a network that funded and supported Ariel Community Academy.[13] In 1999, he became Deputy Chief of Staff for former Chicago Public Schools CEO Paul Vallas.[14] Mayor Richard M. Daley appointed Duncan to serve as CEO of Chicago Public Schools on June 26, 2001.[15]

Duncan was a fellow in the Leadership Greater Chicago's class of 1995[16], and a member of the Aspen Institute's Henry Crown Fellowship Program, Class of 2002. In May 2003, he received an Honorary Doctor of Laws degree from Lake Forest College.

On December 16, 2008, President-elect Barack Obama nominated Duncan for Secretary of Education. Duncan had known Obama for over a decade and played recreational basketball with him, including the day Obama was elected president[17]. Duncan was confirmed by the full Senate on January 20.[18][19]

Here is a backroom meeting on the westside of Chicago with some major players..A tip was given regarding this meeting to discuss the closing of Collins High School to turn them into Daley ran Charter Schools public schools on the Westside. We don't know what WAS being discussed but it sure looks shady

"Selling out the community Danny Davis, Ricky Hendon, Michael Scott and Arne Duncan Part 1of 3"

"Selling Out the Community Danny Davis, Rickey Hendon, Arne Duncan and Michael Scott Part 2"

"
Selling out the community Danny Davis, Ricky Hendon, Arne Duncan and Michael Scott Part 3"

So, while I know it's not conclusive, based on the above videos I think a strong case can be made for Michael Scott being left-handed.

Beyond that, the videos speak for themselves. I think they provide a fascinating inside glimpse at Chicago politics, although I hope they do not represent a behind-the-scenes look at some of the people who are now governing the country.

Far be it from me to help shed unwanted light on larger issues.
