PARIS - French investigators began taking DNA samples Monday from 527 male students and staff at a high school - including boys as young as 14 - as they searched for the assailant who raped a teenage girl on the closed campus.

Testing began Monday at Fenelon-Notre Dame high school in western France. All those who received summonses last week were warned that any refusal could land them in police custody, and no one rejected the sweeping request to test the high school's male population.

The testing of students, faculty and staff at the school is expected to last through Wednesday, with 40 DNA swabs recovered inside two large study halls. Prosecutor Isabelle Pagenelle said investigators had exhausted all other leads in the Sept. 30 rape of the girl in a dark bathroom at the school.

"The choice is simple for me," she said. "Either I file it away and wait for a match in what could be several years, or I go looking for the match myself."

While there have been other situations in which DNA samples have been taken en masse, the case is complicated for France, where acceptance is widespread for DNA testing and a national database maintains profiles of people detained for even minor crimes. But children's civil liberties are considered sacred, especially within schools.

France has stringent privacy protections - Google, for example, has come under legal attack for storing user data, as well as for lapses in images from Street View. Questions of criminality are a different matter - the government's DNA database has expanded radically since it was first created in 1998, and now encompasses 2 million profiles, or about 3 percent of the population.

"It's clearly a situation where people do not have a choice," said Catherine Bourgain, a genetic researcher and author of "DNA, Superstar or Supercop." ''One you have a DNA file it's very difficult to get that information erased."

Authorities have promised to discard the DNA collected once a donor is eliminated as a suspect, but Bourgain said she hoped that would also include the profile information, which during the usual course of French investigations is computerized and transmitted to the database.

Police recovered genetic material from the girl's clothing but found no matches among current profiles.

527 potential suspects in French high school rape lead to mass DNA test

French police are demanding DNA samples from 527 male students and staff members in its search for the perpetrator of a high school rape case. The teenage victim says that she cant identify her assailant since he attacked her from behind in a dark bathroom at the school on Sept. 30. After running out of leads the police tested DNA recovered from the girls clothes but found no match in the countrys database authorities have decided to simply take DNA samples from every male who was on the closed campus at the time of the alleged rape. The testing began Monday.

Authorities have warned students and staff that if anyone opted not to give a DNA sample he would be considered a suspect and taken into custody.Its clearly a situation where people do not have a choice, Catherine Bourgain, a genetic researcher and author of DNA, Superstar or Supercop, told the Associated Press. Once you have a DNA file its very difficult to get that information erased. So far, nobody has refused to give over a sample, prosecutor Isabelle Paganelle told the Associated Press.

The choice is simple for me, Paganelle said. Either I file it away and wait for a match in what could be several years, or I go looking for the match myself. Authorities promised to trash the samples of the children under investigation once each student was eliminated as a suspect.

The head of the school agreed that asking for DNA samples from every man at the school was the right decision. This happened during the school day in a confined space, Chantal Devaux, the private Roman Catholic schools director, told French media. The decision to take such a large sample was made because it was the only way to advance the investigation.

Though the mass DNA sampling may seem like the logical conclusion for the French police, its unlikely that U.S. authorities would take similar steps to catch a rapist. The cost alone a reported $6,900 would likely be a deterrent.

But the more pressing issue is one of privacy. The Fourth Amendment to the United States Constitution prohibits unreasonable search and seizure without a warrant backed by probable cause. This includes seizure of DNA. The American Civil Liberties Union called it a serious blow to genetic privacy when the Supreme Court ruled 5-4 in June of 2013 that police may take DNA samples from people after they are arrested in connection with a serious crime: The ruling allows the police to seize the DNA of innocent Americans who have never been convicted of any sort of crime, without a search warrant. Imagine what the ACLU would have to say about police taking DNA samples before they obtained a warrant.

American authorities would have a hard time arguing that 500 people attending school would constitute probable cause for search and seizure of the students DNA. And it would certainly cause an uproar if police in the U.S. were able to take someone into custody for refusing to voluntarily provide a DNA sample. Though the technology is relatively new, the principle is as old as the Fourth Amendment itself.

So we probably wont be seeing such tactics employed by American police any time soon. But there are also larger questions about an emerging concern for rape culture at play. My colleague Charlotte Alter argued last week that rape culture and sexual assault awareness can unfairly place good guys under suspicion for acts they would never commit: this incident seems to be the prime example since the police are arguing that every male in the school is a suspect merely because of their location and chromosomal makeup.

Then again, however problematic the tactic may be, its heartening to see the French police force take such a proactive stance on identifying a rapist when there is a backlog of 400,000 rape kits still waiting to be tested in the U.S.
