This is getting ridiculous. First there is the shooting at a Colorado Church and now there is the shooting at a Nevada School Bus stop. Before that there was the shooting at the Nebraska shopping mall. Clearly, people need to be on guard at all times, even in church.
So pay attention people! If you read the article highlighted above, the only reason the death toll in Colorado was so low is because of an alert security guard. You and you alone are responsible for your own security.
