“I am deeply distressed by the recent shooting in Las Vegas and send my thoughts and prayers to the victims and their friends and families. This is particularly painful since it is one more shooting on a list of 13 mass shootings that have occurred since 2012. We don’t know the reasons behind all of the shootings and may never find out, but we do know one thing. All of the shooters were men. They were men of different races, ages, religions, and backgrounds, but they were all male.
