Six years later, in an about-face, the FBI admits that federal agents fired tear gas canisters capable of causing a fire at the Branch Davidian compound near Waco, Texas in 1993. But the law enforcement official said the firing came several hours before the structure burst into flames, killing 80 people including the Davidians’ leader, David Koresh.
"In looking into this, we’ve come across information that shows some canisters that can be deemed pyrotechnic in nature were fired—hours before the fire started," the official said. "Devices were fired at the bunker, not at the main structure where the Davidians were camped out."
The Federal Bureau of Investigation maintains it did not start what turned to be a series of fiery bursts of flames that ended a 51-day standoff between branch members and the federal government. "This doesn’t change the bottom line that David Koresh started the fire and the government did not," the official said. "It simply shows that devices that could probably be flammable were used in the early morning hours."
The law enforcement official said the canisters were fired not at the main structure where the Davidian members were camped out but at the nearby underground bunker. They bounced off the bunkers concrete roof mad landed in an open field well, the official said. The canisters were fired at around 6 a.m., and the fire that destroyed the wooden compound started around noon, the official said. The official also added that other tear gas canisters used by agent that day were not flammable or potentially explosive.
While Coulson denied the grenades played a role in starting the fire, his statement marked the first time that any U. S. government official has publicly contradicted the govemment’s position that federal agents used nothing on the final day of the siege at Waco that could have sparked the fire that engulfed the compound. The cause of the fiery end is a major focus of an ongoing inquiry by the Texas Rangers into the Waco siege.

【单选题】Which of the following statements is NOT true according to the passage() A. Even the able-bodied may lose some of their body functions when they get older. B. There are about 10 percent disabled perso...

A.
No one knows exactly how many disabled people there are in the world, but estimates suggest the figure is over 450 million. The number of disabled people in India alone is probably more than double the total population of Canada.
B.
In the United Kingdom, about one in ten people have some disability. Disability is not just something that happens to other people: as get older, many of us will become less mobile, hard of hearing or have failing eyesight.
C.
Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many progressive disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form of a mental illness. All are affected by people’s attitude towards them.
D.
Disabled people face many physical barriers. Next time you go shopping or to work or visit friends, imagine how you would manage if you could not get up steps, or on to buses and trains. How would you cope if you could not see where you were going or could not hear the traffic But there are other barriers: prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through, so it is important to draw attention to these barriers and sow that it is the individual person and their ability, not their disability, which counts.
