The short answer is no. For the long answer, buckle up and keep reading, as I will give you some mind blowing facts.
FBI’s role in the Las Vegas shooting is massive, especially regarding forensics, which are all performed in FBI’s laboratories by their highly trained techies. FBI is in charge of vital laboratory analyses of weapons/ammo/bullet angles, cartridges, residue, weapons modifications, which will reveal from what weapons did bullets come from, what type of bullets were found in the victims, and so forth and so on.
After analyzing the forensic evidence, FBI will be able to tell us if there were multiple shooters or not, provided they can be trusted with telling the truth. The problem is, the FBI has a long history and a scurrilous reputation for lying to the American public on countless occasions.
If you remember the Oklahoma City Murrah Federal Building bombing, when 169 people where killed and 680 were wounded on April 19, 1995, let me tell you some facts: Tim McVeigh, Terry Nichols, and Michael Fortier were arrested and convicted for the bombing, with the former being put to death in 2011. Terry Nichols is currently serving multiple life sentences with no parole and Fortier was released after being sentenced to 12 years in prison. According to the official narrative courtesy of FBI, the bombing occurred as a Ryder truck filled with barrels of ammonium nitrate plus fuel oil (ANFO bombs) was parked outside the Murrah Building then detonated at approximately 9 a.m. on April 19th 1995.
FBI’s forensics investigation determined/concluded that all the death and damage was caused by the ANFO bombs in the Ryder truck.
However, after 2 years, i.e. in 1997 on March 22nd, here comes CNN with a jaw dropping report(they were not so much in the fake news business then):
“The Justice Department inspector general’s office has determined that the FBI crime laboratory working on the Oklahoma City bombing case made ‘scientifically unsound’ conclusions that were ‘biased in favor of the prosecution,’ The Los Angeles Times reported Saturday.”
“…[FBI] supervisors approved lab reports that they ‘cannot support’ and…FBI lab officials may have erred about the size of the blast, the amount of explosives involved and the type of explosives used in the bombing[!].”
“…harshest criticism was of David Williams, a supervisory agent in the [FBI] explosives unit, the paper [LA Times] said. Those flaws reportedly include the basis of his determination that the main charge of the explosion was ammonium nitrate. The inspector general called such a determination ‘inappropriate,’ the Times said.”
“…FBI officials found a receipt for ammonium nitrate at defendant [Terry] Nichols’ home and, because of that discovery, Williams slanted his conclusion to match the evidence.”
However, the fake FBI science was allowed to stand. More recently, stories about the incredible corruption in the FBI’s forensics/evidence labs surfaced in 2014 and in 2015:
…the Washington Post made clear Saturday in an article that begins with a punch to the gut… ‘Nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000,’ the newspaper reported, adding that ‘the cases include those of 32 defendants sentenced to death’.”
April 20, 2015, The Atlantic
“…the initial results were released of an ongoing review of thousands of criminal cases in which FBI scientists’ testimony may have led to wrongful convictions – including for some people now on death row…[an FBI source states] ’we teach these people [lab techs in training] for two weeks, and they would go back to their laboratories with a certificate of completion and be told: Great you’re qualified to do this [analysis of evidence] – here’s your caseload.’”
August 12, 2014, New Scientist
“The Justice Department and FBI have formally acknowledged that nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000.”
“Of 28 examiners with the FBI Laboratory’s microscopic hair comparison unit, 26 overstated forensic matches in ways that favored prosecutors in more than 95 percent of the 268 trials reviewed so far, according to the National Association of Criminal Defense Lawyers (NACDL) and the Innocence Project, which are assisting the government with the country’s largest post-conviction review of questioned forensic evidence.”
“The cases include those of 32 defendants sentenced to death. Of those, 14 have been executed or died in prison, the groups said under an agreement with the government to release results after the review of the first 200 convictions.”
Washington Post, April 18, 2015
Bottom line, there’s little reason to trust the FBI when it comes to anything, including the Las Vegas massacre, whether we’re talking about Paddock’s motives, his weapons/ammo/modifications, the degree of his involvement (or lack thereof) and so forth and so on.
