I've never liked the term Homicide Bomber. I know that it is used to emphasize the "homicide", but just about any bomber is a homicide bomber. Eric Rudolph is a "homicide bomber". Suicide bombers kill themselves and others too.
I agree, although some people dislike "suicide bomber" because they feel it gives to much attention to the perpetrator rather than to the victims. I think the terms keeps our focus on the disregard they feel for life--that they are willing to kill themselves to impose their twisted ideology on everyone else.
