We consider driving under the influence of alcohol or while texting as a cause of road fatalities. This is in spite of the possible fact that most people can drive safely under the influence of alcohol or while texting. We do not concern ourselves with the statistics of how many can drive safely. We do not use such statistics to ignore the fatal actions of certain people who drink or text while driving.
Likewise, we know that many people murder other people due to their interpretation of their religion, Islam. We must not concern ourselves with the statistics of how many religious people of the Islamic religion are peaceful, good people. We must not use such statistics to ignore the reality of certain fatal interpretations. This means we are obligated to investigate the possible religious influences of the Boston massacre killers. We need to clarify if they attended a house of worship where the preacher influenced them. This does not mean the preacher was involved.
