His check of multiple victim shooters indicates that these murderers are not religious individuals. I have never really compiled this information myself, though I seem to recall at least one case in Seattle where I thought that the killer was Islamic, but in any case, I accept his statement that it is quite rare that these killers are religious. Dennis' point was that if all these people were religious, the media would have made an issue of it. The fact that they are not religious makes it not interesting to the media. I think that he is correct on this.
I also agree with his concern that it is extremely disappointing to see the murderer's death included in the victim count. I have been bothered by this for years and I am glad to see Dennis mention this.
