Investigations by three newspapers caught our eye this week.

Over the weekend the Philadelphia Inquirer launched a three-day series focusing on the large number of nuisance arrests by suburban police departments. The Inquirer found that three Philadelphia-area, blue-collar towns were among the top 15 in the nation for such arrests, which include loitering, noise, disorderly conduct and other violations. The paper's reporting showed that the arrests generally involve the predominately white police departments in confrontations with black defendants, adding to racial tensions.

Early in the week, the Fort Lauderdale Sun-Sentinel reached a settlement in its lawsuit against the federal government for the names and addresses of individuals receiving disaster payments from the Federal Emergency Management Agency. The Sun-Sentinel began digging into FEMA in 2005, after Florida was hit by a series of hurricanes. The managing editor said the effort was the paper's "longest-running, most-exhaustive, most-successful investigative project." The work included 75 stories written over 17 months and found that $330 million in FEMA money had gone to counties that suffered no damage. Under the settlement, the government agreed to pay the paper $146,096 in legal fees and hand over information about 1.3 million disaster aid recipients nationwide.

Finally, today the New York Times published its examination of the $500 million raised by Bill Clinton's foundation, which funds his library and globe-trotting philanthropy. The paper reported that $31.3 million had come from one donor, the Radcliffe Foundation, run by Frank Giustra, a Canadian who made his fortune from international mining concerns. The foundation said in a statement that none of the donors sought or received favors from Clinton when he was in power. The paper said it had compiled the first comprehensive list of the 97 donors who had pledged or given $69 million to the library in the final years of the Clinton administration. Last week, The Post reported that at least 10 percent of the library's $165 million cost had come from foreign sources.
