Well color me ignorant. I must know much less than your mama about weapons, but of course so did the FBI and the Army marksmen that tried to repeat Oswald's amazing feat and completely failed. Of course a US ex-marine would pick up an imported Italian rifle that he wasn't familiar with or trained to use because, well, I don't know why a marine would throw his edge away. None of the marines I know would do such a thing (though I do know a couple vets around here that like and keep a number of Russian weapons).

And no, I don't have a link. I just have an excellent retentive memory from information read years ago before there was such a thing as an internet. Those funny paper thingies...books I think they were called. :-)

Underrated and under-collected. Might be a reason for that, ya think? Along with there having been much more accurate sniper weapons easily available in those days at any gun store or military surplus auction.

Eight year old long debunked early reporting mistakes are the best you can do?

"Hijackers still alive?

This claim is based on a report by the BBC on September 23, 2001.[7] The BBC has since reported about the 19 hijackers,[8] and has issued corrections to this story.[9]

In the aftermath of the attacks, there was confusion about names on the list issued by the FBI, as well as lists obtained by the Boston Globe and other media outlets.
Waleed al-Shehri

There was confusion regarding one name on the list -- Waleed Alshehri. In a case of mistaken identity, a different Waleed Alshehri (other than the real hijacker) was initially identified. This Waleed Alshehri came to Daytona Beach, Florida in 1996, took aviation lessons at Embry-Riddle Aeronautics University,[3] and was employed as a pilot for Saudi Arabian Airlines. He was living in Morocco at the time of the 9/11 attacks.
Abdul al-Omari

There was also confusion regarding Abdul al-Omari. Someone with a similar name in south Florida, Abdulrahman S. Alomari, took flight lessons at Flight Safety International. He was identified early and confused with the hijacker.[10] Abdulaziz Alomari, a 28-year old in Riyadh, said his passport was stolen while he lived in Denver in 1995, and thought his identity was stolen by one of the hijackers.
Saeed al-Ghamdi

Said Hussein al-Ghamdi, a Saudi pilot living in Tunis, was also mistaken, with CNN broadcasting his picture instead of that of Flight 93 hijacker, Saeed al-Ghamdi.
Marwan al-Shehhi

The list obtained by the Boston Globe on September 12 included the name Marwan Alshehri. (name really is Marwan al-Shehhi)[11]
Khalid al-Mihdhar

In the aftermath of the September 11 attacks, some news reports showed a picture of Khalid Al-Mihammadi, a computer programmer from Mecca, in place of Khalid al-Mihdhar's picture. Mihammadi had been in the United States to study English in Florida, and in Indiana.[12] One story, published by the BBC on September 23, indicated that Mihdhar was possibly still alive.[13] In 2006, in response to 9/11 conspiracy theories surrounding its original news story, the BBC claimed that confusion arose with the common Arabic names, and that its later reports on the hijackers superseded its original story.[14]
Why the confusion?

* One source of confusion is the fact that hijackers often varied the spelling of their names when renting rooms, banking, and other activities. For example, Hani Hanjour, whose full name is "Hani Saleh Hanjour", also used "Hani Hanjoor", "Hani Saleh", "Hany Saleh", and "Hami Hanjoor".[15]
* Also, some of the names, particularly "al-Ghamdi" and "al-Shehri" are extremely common names in Saudi Arabia, as Smith is common in the United States.[16]

Arab News explained how names and photographs of Saudi pilots trained in the U.S. were published and mistaken for the hijackers.
“ In the rush to reveal information, these were published without due authentication. According to a US source, the FBI committed some errors in its inquiries at the beginning of the investigation. First, it asked about pilots or trainees at airlines whose names resembled those of the hijackers. This was on the presumption that the hijackers should be pilots or experts in aviation. This led to the confusion about the names of pilots Saeed Al-Ghamdi who turned up in Tunis, Abdul Rahman Al-Amri who was in Jeddah and Waleed A. Al-Shehri, who showed up in Rabat. These three men have been cleared of any association with the alleged hijackers.[17] ”
