So you are not adult enough to admit the crime scene investigation was started on Sept 21 and ended on Set 26.
The FBI assumed crime-scene jurisdiction at the Pentagon terrorist attack site Sept. 21 from the Arlington County (Va.) Fire Department, officials said.
FBI officials estimate the crime scene investigation would last about a month, Arlington Fire Chief Edward P. Plaugher said. He said he expects "additional remains will be discovered during the course of the FBI investigation" and mortuary specialists will remain on site to process them.
Look, you can continue your spasm of reporting posts, but you appear to have suffered a breakdown. You are trying to pretend that FBI agents who arrived immediately after the crash did no investigative work for ten days. I'm sorry if you're offended, but your claim, if we are to take it literally, is insane. There is no more precise word to describe it.
