Grassy knoll/2nd shooter scenario back on the table for JFK hit

My own belief is that there was a second/third shooter and Oswald was just a convenient patsy.

LIVERMORE -- ...metallurgical chemical "fingerprints" on the bullets that killed the president and wounded then Texas Governor John Connally may have been misinterpreted and that the government's crucial "single gunman theory" has been thrown into doubt.

"It basically shatters what some people call the best physical evidence around,"...

...chemical "fingerprints" used to identify which bullets the fragments came from were not quite the "smoking gun" as thought pointing to Lee Harvey Oswald as the lone gunman.

The FBI used five bullet fragments..."neutron activation" analysis...Randich said the Lawrence Livermore tests came to a different result.

"We don't know if there were two bullets," said Randich. "There could have been two bullets, but the lead composition data shows there could be anywhere from one to five bullets."
