Was Oswald Lone JFK Gunman?

Bullet analysis used to justify the
lone assassin theory behind President John F. Kennedy's
assassination is based on flawed evidence, according to a team
of researchers including a former top FBI scientist.
Writing in the Annals of Applied Statistics, the
researchers urged a reexamination of bullet fragments from the
1963 shooting in Dallas to confirm the number of bullets that
struck Kennedy.

Official investigations during the 1960s concluded that
Kennedy was hit by two bullets fired by Lee Harvey Oswald.

But the researchers, including former FBI lab metallurgist
William Tobin, said new chemical and statistical analyses of
bullets from the same batch used by Oswald suggest that more
than two bullets could have struck the president.

"Evidence used to rule out a second assassin is
fundamentally flawed," the researchers said in their article.

"If the assassination (bullet) fragments are derived from
three or more separate bullets, then a second assassin is
likely."
The Kennedy assassination set off a whirlwind of theories
about who killed the 46-year-old president.

The President's Commission on the Assassination of
President Kennedy, known unofficially as the Warren Commission,
concluded in 1964 that Lee Harvey Oswald, acting alone, fired
three shots, one of which missed the president's car. There
have been many challenges to its conclusions over the years.

The House of Representatives  Select Committee on
Assassinations concluded that Oswald was probably part of a
conspiracy that could have included a second gunman who fired
but missed Kennedy.

The panel's supporting evidence was a bullet analysis that
said fragments collected from the site were too similar to be
from more than two slugs.

But the latest report found that many bullets from the same
batch used by Oswald had a similar composition.

"Further, we found that one of the thirty bullets analyzed
in our study also compositionally matched one of the fragments
from the assassination," the article said.

"This finding means that the bullet fragments from the
assassination that match could have come from three or more
separate bull
