NASA pledges to review security policy after gunman kills hostage
NASA has decided to re-examine it's security after an employee smuggled a handgun into the Johnson Space Center and killed a hostage and then himself. 60-year-old Will Phillips had apparently had a disagreement with 62-year-old David Beverly before shooting him. The ordeal lasted several hours.
The New York Times added that the center had already reviewed its security policies after the Virginia Tech shootings earlier this week.
Both stories do a good job in attribution and are plentiful in quoted matter. I like that the New York Times related the incident to other recent news.
