Thankyou for your kindness,you seem to grasp what really troubles me about my daughters death. Diving as everyone says, is a dangerous sport which comes with high risk. But as in any high risk activity their must be a goal toward higher awareness, and knowledge. More focus has to be put in training on how to save yourself and that the buddie system is just a long shot last resort, especially if your picking up buddies on recreational trips that you don't really know. This sight is great for spreading awareness , but some people just need to be taught the serious commitment that comes with diving and that you should always be trying to learn more. This is what I believe is not being laid out in that first dive in that swimming pool, if it was you could wash out alot of divers that don't understand the serious side of this sport.
