***** To join INSNA, visit http://www.sfu.ca/~insna/ ***** I reiterate: There are clear issues of data quality here. Police often make charges that turn out to be false. The overall project will be interesting in terms of how you will want to deal with this. I would recommend that, once you have made your "best estimate" as to which characterizations are real, you might want to do some sensitivity analyses. For example, assume that some percent of the characterizations you discarded as unreal were real; and some percent of the characterizations you accepted as real were not. I would suggest using fairly high percents (30% - 70%) in terms of police allegations that people are dealers or terrorists. If the allegations proved out in a jury trial, I might lower this by quite a lot; but if (in the USA at least) a person pled guilty, this is often just a statement of helplessness and thus may have little impact on the percents (30 - 70) I suggested above. It should prove interesting. best sam Sam Friedman National Development and Research Institutes 71 West 23d Street, 8th floor New York, NY 10010 USA 1 212 845 4467 Fax 1 917 438 0894 [log in to unmask] >>> John Taylor <[log in to unmask]> 8/3/2004 3:46:14 PM >>> ***** To join INSNA, visit http://www.sfu.ca/~insna/ ***** FYI - The recent train bombing was coordinated with the help of a major drug dealer and the explosives were exchanged for drugs. You can probably find out more about it in open source / Internet accounts. Good hunting. JT Lebanese man arrested over Madrid train bombings By ASSOCIATED PRESS Advertisement MADRID, Spain A Lebanese man with a police record for drug trafficking was arrested in connection with the March 11 train bombings in Madrid, officials said Thursday. Semaan Gaby Eid was detained Wednesday night outside his home in Madrid's Carabanchel neighborhood, police and Interior Ministry officials said. He was not immediately charged, but cell phones, bank statements and documents were confiscated as possible evidence, according to a ministry statement. "He is a person whom we consider to be linked directly to suspects who are in jail," police spokesman Antonio Nevado said in a telephone interview. More than 50 people have been arrested so far and 16 are in prison, including at least two who allegedly were directly involved in the bombings. Most are Moroccan. Islamic militants with suspected ties to al-Qaida are blamed for the attack - nearly simultaneous blasts that ripped through four commuter trains, killing 191 people and injuring more than 1,600. The Lebanese man arrested Wednesday was allegedly traced to the suburban Madrid neighborhood of Leganes where seven suspects blew themselves up on April 3 in an apartment as police were closing in on them. The Interior Ministry said he was carrying false documents identifying him as Gabriel Salim Aoun, born in Mozambique in March 1960. Just hours after the bombings, the suspect was in the area of a farmhouse outside Madrid where the bombs were prepared, the ministry said. "We have had witness verification, but I cannot reveal any more details about that," Nevado said. _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.sfu.ca/~insna/).
