Indeed, Twitchy makes sure that Twitter is forever.

But the reports on several news sites are false: Ex-“CSI” actress Marg Helgenberger has not deleted the tweet that appeared to call for violence against gun owners.

Helgenberger’s tweet, just hours after the horrific shooting massacre at Sandy Hook Elementary School, was in response to author Joyce Carol Oates’ hope that there might be gun control “if sizable numbers of NRA members become gun-victims themselves.”

As of 10:00 a.m. on Thursday, Dec. 20, neither tweet has been memory-holed.

Not only does the tweet still sit on Marg’s account, but she hasn’t even bothered with one of those pesky non-apology apologies. She tweeted twice yesterday, and neither tweet acknowledged her appalling “hope” for the shooting of NRA members.

“All’s well.” She’s just too “busy” to respond to critics of her sick tweet. But, you know, “Happy Holidays!”
