While I hope that the shooter is caught and feel bad that an apparently innocent person was injured, I cannot help but think what would have happened if the shooter had stuck around and kept shooting. I think this, if the circumstances are as they appear, is a clear example of why we need to go to a "shall issue" concealed carry law. Even under the best of circumstances it would be almost impossible for the police to respond in time to catch, let alone prevent, a more dedicated shooter. That being the case, I find it incredible that otherwise law abiding citizens are denied the ability to protect themselves and their family from sociopaths such as the person that shot at this family.
I know, I'm preaching to the choir....
