[More in the cross-post on the MRC's NewsBusters blog.]Carol Costello surprisingly raised pro-gun rights points during an interview of Senator Richard Blumenthal on the 27 May 2014 edition of CNN Newsroom. Costello noted the "renewed calls for stricter gun control laws" after Friday's murder spree in California, and pointed out that the Golden State "has some of the strictest gun laws in the country. The shooter in this case abided by a background check....How would any gun control law prevent this particular shooter from buying a gun?"The anchor, who has forwarded gun control in the past, also zeroed on the fact that the deceased murderer began his rampage by stabbing three people to death:CAROL COSTELLO: ...The shooter, [Elliot] Rodger – he used a knife, too. He used a knife to kill three people, and then, he used a gun to kill three more. Some argue if a deranged person wants to kill, they will find a way. It's the argument that gun control advocates cannot seem to win with those who – who passionately believe in gun rights. So, how do you compromise?
