Just a suggestion, if the conversation is not to your liking, you can always step away and come back later - or you can skip over the posts you don't like. Many people feel after a tragedy like this it's appropriate to keep the atmosphere respectful and focused on the victims, as this is first and foremost a victim friendly site.
Also, it's not a great idea to critisize fellow posters here on WS. So you know-- we're not professional criminal profilers or law enforcement exclusively looking to catch a perp right now, we're human beings many of whom have loved ones in the area and at this time we are grateful to have a forum like WS to come together and mourn.
