THE 57-year-old man charged in the murderous shooting spree at a Planned Parenthood clinic in Colorado allegedly made remarks to police about “no more baby parts.” That has led some to speculate that antiabortion rhetoric sparked the rampage. The suspect’s history of aberrant behavior prompted others to theorize that mental illness was the culprit. In the early stages of the investigation, we don’t know what, if any, role was played by either of these factors. In the meantime it is worth restating the obvious: The one factor common to every terrible case of gun violence is access to guns.
A police officer, an Iraq war veteran and a young mother of two were killed, and nine other people were wounded, in last week’s attack at the health clinic in Colorado Springs. Such mass shootings are all too sickeningly familiar. On the very same Friday after Thanksgiving, two people were killed and two injured in a shooting in Sacramento. In the very same community of Colorado Springs a month ago, a shooter gunned down three people targeted at randombefore being gunned down himself by police.
