  WASHINGTON-According to statistics compiled by the Federal Bureau of Investigation, 72 officers were killed by criminals in 2011, increased markedly in recently years.

  The 2011 deaths were the first time that more officers were killed by suspects than car accidents.The number was the highest in nearly two decades, excluding those who died in the Sept.11 attacks in 2001 and the Oklahoma City bombing in 1995.

  While the F.B.I.and other law enforcement(执行)officials cannot fully explain the reasons for the rise in officer homicides, they are clear about the terrible consequences.

  “In this law enforcement job, when you pin this badge on and go out on calls, when you leave home, you can't guarantee that you will come back,” said Sheriff Ray Foster of Buchanan County, Va.

  After a series of killings in early 2011, Attorney General Eric H.Holder Jr.asked federal authorities to work with local police departments to try to come up with solutions to the problem.

  The F.B.I., which has tracked officer deaths since 1937, paid for a study conducted by John Jay College that found that in many cases the officers were trying to arrest or stop a suspect who had previously been arrested for a violent crime.

  That prompted the F.B.I.to change what information it will provide to local police departments, the officials said.Starting this year, when police officers stop a car and call its license plate into the F.B.I.'s database, they will be told whether the owner of the vehicle has a violent history.Through the first three months of this year, the number of police fatalities has dropped, though it is unclear why.

  Some law enforcement officials believe that techniques pioneered by the New York Police Department over the past two decades and adopted by other departments may have put officers at greater risk by encouraging them to conduct more street stops and to seek out and confront(对抗)suspects who seem likely to be armed.In New York and elsewhere, police officials moved more officers into crime-ridden areas.

  Some argue that the rise in violence is linked to the tough economy.With less money, police departments, after years of staffing increases, have been forced to make cutbacks(削减).

  The police chief in Camden, N.J., J.Scott Thomson, whose force of 400 was cut by nearly half last year because of financing issues, said that having fewer officers on the street “makes it that much more difficult to create an environment in which criminals do not feel as encouraged to attack another person, let alone a law enforcement officer.”

  “Every stop can be potentially fatal, so we are trying to make sure the officers are ready and prepared to face deadly force every single day they go out.” Ms.Klimt said.

  The United States government wants to know what the public thinks about its findings on the safety of cloned animals.

  The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat.An F.D.A.official called them "as safe to eat as the food we eat every day." And when those clones reproduce sexually(有性繁殖), the agency says, their offspring(后代)are safe to eat as well.But research on cloned sheep is limited.So the F.D.A.proposes that sheep clones not be used for human food.

  The United States this year could become the first country to approve the sale of foods from cloned animals.First, however, the public will have ninety days to comment on three proposed documents.On December 28th the F.D.A.released a long report, called a draft risk assessment, along with two policy documents.

  The agency says it must receive comments by April second.The F.D.A.seemed ready to act several years ago, but an advisory committee called for more research.

  For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.

  Clones are still rare.They cost a lot and are difficult to produce.

  The F.D.A.says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring.It says clones are expected to be used mostly as breeding(繁殖)animals to spread good qualities.

  Public opinion studies show most Americans do not like the idea of food from cloned animals.But this research also shows the public knows little about cloning.

  Cloning differs from genetic engineering.A cell taken from a so-called donor(捐赠者)animals is grown into an embryo(胚胎)in the laboratory.Next, the embryo is placed into the uterus(子宫)of a female animal.If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born.
