Keeping them honest: Is the IRS targeting whistleblowers?
P. Jeffrey Black bumped up against his bosses in the Federal Air Marshal Service, eventually becoming a whistle-blower and testifying to a closed-door congressional hearing before his retirement in 2010.
He had taken a long list of complaints to lawmakers about how the air marshals service was run, ranging from problems keeping marshals on flights to allegations of ineptitude and favoritism by managers. The same year he retired, he appeared in "Please Remove Your Shoes," a documentary critical of the airline security measures travelers endure on every trip.
Then came the audit, which an Internal Revenue Service agent told him about the same day the movie premiered - "almost to the hour," he said.

Keeping Them Honest: Deadly bacteria in VA hospital
As AC360 first reported back in December 2012, the Veterans Administration hospital in Pittsburgh had high levels of Legionella bacteria in its water supply, but for months failed to solve the problem.
Staff and patients weren't made aware of the issue, and at least five patients died. Eventually drinking fountains were sealed off and patients stopped getting baths and showers, but it was too late for some of those who came into contact with the bacteria.
Victims' families are livid about how the problem was mishandled. "There were deaths before him that we didn't know about. We wouldn't have gone there ... He had a good outlook on life. He felt he had more time left," says Sandy Riley whose brother Mitch Wanstreet died after contracting Legionnaire's disease at the hospital.

KTH: Cold case didn't have to go cold
CNN's Drew Griffin reports on the leads Mississippi law enforcement ignored in the 2009 roadside killing of Garrick Burdette. The police recently released information about his death to a local newspaper after Griffin questioned them about the way they handled the case.
Burdette's mother told Anderson Cooper it's hurtful that authorities only contacted her about her son's death after CNN put a spotlight on the story, more than three years later. The investigator apologized to her for letting the case slip through the cracks.
Now police say a suspicious car was at the scene of the incident. The article says a deputy thought about trying to find that car, but didn't. There were other clues about the vehicle that could have helped track down the driver, but there was no investigation.
KTH: No investigation after fatal hit and run
Two hit-and-run deaths in rural Mississippi just a few miles apart highlight a disturbing problem about data collection on possible hate crimes.
Last summer, 61-year-old African-American Sunday school teacher Johnny Lee Butts was hit and killed by an 18-year-old white driver. The teen told Panola County Sheriff deputies he thought he hit a deer but the driver's two passengers said he steered straight for Butts. One passenger said he could see that Butts was black. The killing has sparked outrage in the local African-American community. Civil rights groups have demanded that police prosecute Butts' killing as a hate crime.
Nonetheless, prosecutors chose not to.
There was no evidence, authorities said, to suggest a racial motive. The driver was charged with murder. He has not yet pleaded in the case.
