From American Life League:
Abortions in the United States
Total number of abortions in the U.S. 1973-2011: 54.5 million+
234 abortions per 1,000 live births (according to the Centers for Disease Control)
Abortions per year: 1.2 million
Abortions per day: 3,288
Abortions per hour: 137
9 abortions every 4 minutes
1 abortion every 26 seconds
Technically, that would be serial killing instead of mass murder. Mass murderers usually know their victims.
Your post exactly expresses my initial reaction to the article.
Two patients enter an abortion clinic, only one comes out alive!
