Troy Davis denied clemency

Death-row inmate Troy Davis, who has been fighting for years to stave off his execution, was denied clemency by the Georgia Board of Pardons and Paroles, a decision that has drawn outrage and protests. Recent evidence casts some doubt on his conviction in the 1989 death of off-duty police officer Mark MacPhail, including the fact that seven of nine witnesses have recanted testimony that led to his conviction.

Davis is scheduled to die by injection Wednesday night in Jackson, Georgia. CNN.com readers debated whether Davis should be executed and whether the death penalty should be a thing of the past.

TooRelaxed said, “If there is one inch of doubt then the death penalty needs to be stopped. There have been a lot of prisoners put to death only later on in years to be found to be innocent.

KCWildguy responded, “A lot? Can you name one? Exactly. So we know 100% that he shot the guy at the party. We know he pistol whipped the homeless guy, but we're playing games that he didn't also kill the cop? How can anyone reasonably think this thug didn't do it?"

Robert (Atlanta) said, “Vengeance does not equal justice.”

Calvin said, “Only God and (Troy) know the truth. I don't believe in the death penalty. Only God has the right to take someone’s life. Whether guilty or not guilty, man should not have the right to justify killing someone else. What if this man really is innocent?”

Kapinatl said, “Over 2000 years ago a man who was also accused was put to death by a crowd who shouted 'crucify him' much like what I have read above. I am curious as to how many of you who feel this man should die attend church?”

Andy W said, “So he admits shooting the first man in the face, then pistol whipping the homeless man; the defense is now trying to twist the testimony to indicate doubt. This man had a fair trial and was found guilty, nothing that the defense has used proves the jury was wrong. This case has been reviewed and reviewed, carry out the jury's sentence.”

Jake M responded, “No, the county alleges that, based on the testimony of the other suspect. Who, by the way, was witnessed by police beating the homeless man with the gun in question. Now do you understand the doubt?"

Scott said, “Most of you people wanting him spared the death penalty don't even care if he's innocent or not. You have your cause and it’s not even him. You're against a punishment.”

Free3 responded, “Life in prison is a punishment. Taking someone’s life is not democratic at all. We are the only Western country that still thinks that murder is legal and not at the same time.

Mauro said, “I'm so glad I left that part of the world a long time ago. Ignorance and racism is the word of the day. Georgia is never on my mind!! Backwards and racist.

Me responded, “Racism has nothing to do with this. Eye for an eye.” But Jomm responded, “You are blind if you think race has nothing to do with this.” And Jessica J said, “An eye for an eye leaves the whole world blind.

End of 'don’t ask, don't tell' celebrated

At 12:01 a.m. Tuesday, the "don’t ask, don’t tell" U.S. military rule became a thing of the past and some gay military members celebrated. One couple even got married at the exact minute the rule ended.

CNN.com readers were largely supportive of the repeal.

PritTX said, “It's about time this outdated law is repealed. I don't care what you do in the bedroom; if you're fighting for my freedom I can only say thank you.”

jdcma said, “Oh, you mean those people who protect my freedoms and are willing to die for our country are able to live with dignity now? It's about F–kn' time. As an American, I'm ashamed it took this long.”

Unchipantsu said, “I am a soldier and I am straight. If having sex with my wife has no affect on the mission, how does a gay or lesbian soldier having sex with their partner affect it?”

Farscape1 responded, “Because apparently all of the homophobes believe that each gay person is a ticking time bomb of lust barely held in check by 'don't ask.' The fact they won't have to hide it anymore seems to mean they'll be constantly jumping the straight soldiers and distracting everyone by checking out people's butts in the middle of a mission.”

jacksays said, "’But a longtime opponent of the change, Elaine Donnelly of the Center for
Military Readiness, says she is concerned that allowing gays and lesbians to serve will drive many loyal troops out of the military.’" Um, she realizes that they've been serving all along, right? Right there beside her and all the rest of our incredible servicemen and women ... this whole time. They've just been denied the same RIGHTS she has, the ability to acknowledge who they are openly and publicly JUST LIKE SHE ALWAYS COULD.”

TimRMartin responded, “Well Jack, it is not they have been denied anything. They have fraudulently joined an organization that specifically forbids (or did forbid) their type of behavior. 'Don't ask, don't tell' did not remove the no homosexuals in the military, it only prevented recruiters from asking about it.”

mb2010a responded, “TimRMartin: Well, Tim. I guess you missed the part that said ‘Servicemembers United said today that 14,346 people were discharged under the ‘don't ask, don't tell’ policy.’”

AL68 said, “I am a conservative who is celebrating the repeal of ‘don't ask, don't tell.’ It is ridiculous to prevent people from serving their country on the basis of sexual orientation. Our nation is founded on the principles of ‘life, liberty, and the pursuit of happiness.’ I implore my fellow conservatives to remember that, and to get on to much more important issues such as job creation and budgetary responsibility.”

SandraWAdams said, “SOOOO grateful that the men and women who we depend on for protection can now expect the same of us!”

Get over clothing sizes

Actress Kirstie Alley, thanks in part to her gig on "Dancing with the Stars," says she has lost 100 pounds and 10 dress sizes, making her a size 4. But "Project Runway" star Tim Gunn thinks Alley may be victim of something he calls "vanity sizing," in which sizes today don’t match what they were 10 or 20 years ago. Regardless, he says people are too size sensitive.

CNN.com readers had plenty to say about Gunn’s size theory and about whether size matters at all.

Mayhem said, “Who cares? She is ultra hot for a 60-year-old. Did you see her on DWTS? She has some curves plus some cool dance moves.”

ToneInNY said, “So does that make what used to be a size 4 now a size 0? And would what used to be a size 2 now be a size -2? Sounds like new math to me. Forget size numbers and adopt the sizing men use, which is in INCHES. The new sizing usage isn't any more vanity sizing than just using the SIZE method to begin with!”

BronxGirl said, “Who cares what dress size you are as long as you feel good and look good? I know when I put on my size 12 dress I feel fabulous and look a lot better than some in a size 4. It's not how much you weigh, it's where you carry it.”

Lizzy10 said, “I usually love Tim, but I have to agree, that was uncalled for. Kirstie looks great.”

Erin said, “So I'm not the only one that thought his analysis was a little over the top for someone saying we're ‘too size conscious?’”

Twinnie said, “I weight 105 pounds and I'm not a size 4 because I'm curvy. The clothing lines have changed the sizing to make women feel better about themselves.”

Feeniegal said, “I agree. Two catalogs I've shopped from for over 10 years advised us that they were adjusting sizes. Last year I ordered some items and they had fliers in the package advising of the new sizing charts. Tim is not lying.”

Christina said, “You are correct about past sizes. Marilyn Monroe was a 12, I think. Today, she'd be a 6, and fashion moguls would complain that she was too big for their clothes to fit properly. Now clothes come in size 00. Have you ever seen a dress form from the '60s? They are tiny and don't even expand to today's sizes. Let's just try to be healthy, whatever weight we are.”

C. Anderson said, “Mr. Gunn is right about dress sizes, but also right that Kirstie looks fabulous. We are so obsessed with sizes, ages, weight and so forth, instead of just aiming to look great, being good people, being healthy and making this world a happier place."
