It's MORNING EDITION from NPR News. I'm Renee Montagne.
STEVE INSKEEP, HOST:
And I'm Steve Inskeep.
For months on this program we've heard evidence of atrocities in Syria. Most recently scores of bodies were found at the bottom of a concrete-lined river in the city of Aleppo.
MONTAGNE: The question now is how to document those crimes and what to do about them. Human rights groups have been calling for war crimes charges against Syrian leaders.
INSKEEP: If a war crimes prosecution should come, Syrians will have one big advantage - the widespread gathering of evidence, often in real time.
NPR's Peter Kenyon has more from Istanbul.
PETER KENYON, BYLINE: After visiting a Syrian refugee camp in southeastern Turkey recently, U.S. Ambassador to Syria Robert Ford reacted sharply to a question that suggested Washington has kept quiet about the Syrian regime's brutal attacks.
AMBASSADOR ROBERT FORD: We have vigorously condemned the bombing of bakeries and the bombing of breadlines and the bombing of hospitals. I met a lot of Syrians, people who had lost brothers, who had lost children, a shocking number of people who had lost spouses, families that have been decimated.
KENYON: Thus far the Obama administration has not joined the calls for war crimes prosecutions but says it is actively supporting efforts to document potential atrocities - by all sides in the conflict.
OLE SOLVANG: (Foreign language spoken)
KENYON: At times, human rights professionals have been able to get into Syria or speak with Syrians who have fled the country in order to gather evidence. In this video from last summer, Human Rights Watch researcher Ole Solvang lays out some of the group's methodology.
SOLVANG: Using information from more than 200 interviews, we've been able to establish the exact location of many of the worst detention facilities. What we have found is that torture in these detention facilities has been systematic and widespread.
KENYON: Experts from previous war crimes prosecutions gathered with Syrian opposition activists recently in Istanbul. There was much discussion about the difficulties in obtaining solid evidence in wartime, but the experts said in one respect the Syrian conflict may be breaking new ground.
MEGAN PRICE: Unlike all of the other situations where we've worked in the past, there is near real-time documentation of the violations - and that's new.
KENYON: Megan Price, with the Human Rights Data Analysis Group, has worked on legal cases examining atrocities in Colombia and Guatemala, and recently was lead author of a U.N. report documenting deaths in Syria. She says modern technology has put the means of evidence-gathering into the hands of ordinary Syrians all across the country.
PRICE: In most crises, in most conflicts, we go in after and ask people to remember: Five years ago, what was it that happened to your brother? And that's not the case now. The case now is someone is taking a video of the protest and someone is taking a video of the funeral, and they're capturing the story in real time. And that really changes the landscape.

KENYON: Which is not to say that all amateur videos could serve as evidence of violations. This brief Syrian video, in which the narrator surveys the destruction inside a building, offers no date, no location, no information that a prosecutor might use to assess if a war crime occurred.
War crimes data analyst Glyn Morgan says the best videos are the ones with the most information. If the allegation is crimes against children, include the date of birth. If building a sectarian or racial case, identify the victim's religion or ethnicity. Nonetheless, Morgan adds, technology has not surmounted one of the major hurdles in these prosecutions - linking the violations to those higher up the chain of command.
GLYN MORGAN: The crime base information, as we call it, which relates to the actual attacks - the dead, the wounded, and so on - in a way that is the easiest to gather. The big challenge comes from linking that crime base to the higher-level commanders. And to do that you need to have inside information.
KENYON: One aspect of the issue that has received relatively little attention is the question of violations by rebel fighters. There is a small but growing pile of evidence pointing in that direction, and human rights advocates say it cannot be ignored.
