Gov. Rick Perry is suggesting that everyone -- but especially public officials -- should be extra cautious after the weekend killings of a Texas district attorney and his wife.
The slayings of Kaufman County District Attorney Mike McLelland and his wife Cynthia came nearly two months to the day after assistant prosecutor Mark Hasse was shot dead in the same county while he walked toward the courthouse.
Asked Monday if public officials should fear for their safety, Perry said: "I would suggest everyone should be careful about what goes on, whether they're public officials or otherwise."
Perry added that he believes there is "a clear concern to individuals who are in public life, particularly those who deal with some very mean and vicious individuals" including white supremacy groups and drug gangs.
The governor said he had no personal knowledge of the investigation.
