Noam Chomsky calls Osama Bin Laden an unarmed victim.:

There appears to have been no attempt to apprehend the unarmed victim

Noam Chomsky claimed there was no evidence that Bin Laden masterminded the September 11, 2001 or 9/11 attacks on New York and Washington:

Nothing serious has been provided since. There is much talk of bin Laden’s “confession,” but that is rather like my confession that I won the Boston Marathon. He boasted of what he regarded as a great achievement.

Presumable Mr. Chomsky missed the video of Bin Laden meeting with 9/11 hijackers Wail al-Shehri and Hamza al-Ghamdi.

Also I’m aware that Mr. Chomsky is a well regarded linguist, how could he misunderstand Bin Laden in the video Osama released on October 29, 2004, days before the Kerry/Bush Presidential Election:

Bin Laden, “We decided to destroy towers in America,” he said. “God knows that it had not occurred to our mind to attack the towers, but after our patience ran out and we saw the injustice and inflexibility of the American-Israeli alliance toward our people in Palestine and Lebanon, this came to my mind.”

In academic circles you would call Chomsky’s false assertions shoddy research. Truth be told Mr. Chomsky jumped the shark after 9/11, comparing the September 11, 2001 attacks on New York and Washington to President Clinton’s decision to bomb a Sudanese chemical plant suspected of being connected to Bin Laden and making nerve gas.

Chomsky defended those comments here:

Noam Chomsky: I mentioned that the toll of the ‘horrendous crime’ of 9/11, committed with ‘wickedness and awesome cruelty’ (quoting Robert Fisk), may be comparable to the consequences of Clinton’s bombing of the Al-Shifa plant in August 1998. That plausible conclusion elicited an extraordinary reaction

Noam Chomsky is in the business of making crazy comparisons, so no surprise he asked what the difference would be if former President George Bush was subjected to the same treatment that Bin Laden received, even stating that Bush has committed worse crimes than Bin Laden:

We might ask ourselves how we would be reacting if Iraqi commandos landed at George W. Bush’s compound, assassinated him, and dumped his body in the Atlantic. Uncontroversially, his crimes vastly exceed bin Laden’s, and he is not a “suspect” but uncontroversially the “decider” who gave the orders to commit the “supreme international crime differing only from other war crimes in that it contains within itself the accumulated evil of the whole” (quoting the Nuremberg Tribunal) for which Nazi criminals were hanged: the hundreds of thousands of deaths, millions of refugees, destruction of much of the country, the bitter sectarian conflict that has now spread to the rest of the region.
