Anyone remember Kathryn Johnston, the 92 year old Atlanta woman who was shot to death during a police drug raid for attempting to defend herself?
The officers involved in the shooting have been indicted:

ATLANTA—- A grand jury indicted three current and former Atlanta police officers in the shooting death of a 92-year-old woman during a drug raid, according to the document unsealed Thursday.
At least one of the men, retired officer Gregg Junnier, planned to plead guilty later Thursday to reduced state charges and also admit to a single federal charge, his attorney told The Associated Press.
Plainclothes police officers with a no-knock warrant raided Kathryn Johnston’s home on Nov. 21 after an informant said he had bought drugs there, according to police. When the men burst in without warning, Johnston fired at them, wounding three, and they fired back, killing her.
Junnier, 40, and Officer J.R. Smith, 35, were charged in the indictment with felony murder, violation of oath by a public officer, criminal solicitation, burglary, aggravated assault with a deadly weapon and making false statements.
Officer Arthur Tesler, 40, was charged with violation of oath by a public officer, making false statements and false imprisonment under color of legal process.

If I remember correctly, the shooting ignited quite a debate in the blogosphere, not only over the propriety of using SWAT teams (breaking in under “knock and announce” warrants) for routine law enforcement, but over whether the police involved were in the right. I realize this is just an indictment, but it now appears that they were in the wrong.
Anyway, in Atlanta at least, the police are changing their procedures:

The case raised serious questions about no-knock warrants and whether the officers followed proper procedures.
Atlanta Police Chief Richard Pennington asked the FBI to lead a multi-agency probe into the shootout. He also announced policy changes to require the department to drug-test its nearly 1,800 officers and mandate that top supervisors sign off on narcotics operations and no-knock warrants.
To get the warrant, officers told a magistrate judge that an undercover informant had told them Johnston’s home had surveillance cameras monitored carefully by a drug dealer named ”Sam.”
After the shooting, a man claiming to be the informant told a television station that he never purchased drugs there, prompting Pennington to admit he was uncertain whether the suspected drug dealer actually existed.

FWIW, I think drug laws invite abuse of process and shoddy law enforcement tactics, and I don’t see the problem going away any time soon.
This comment that Glenn Reynolds quoted last year still applies:

How many more Kathryn Johnstons must we kill before we start talking about an exit strategy in the War On Drugs?

Good question. I don’t know the answer.
UPDATE: Two cops have pleaded guilty. Glenn Reynolds links Patterico and Radley Balko who have details. I like Glenn’s conclusion:

I’d be more impressed with the Democratic candidates if they had united in their opposition to the War on Drugs, which has done the country much more harm, over much more time, than the one in Iraq.
