Thank you Philip, and welcome to DRTV. If you go through the past pages of this forum, you will find many postings regarding the paramount issue to gun owners, hunters, competitive shooters, and all the above...
That is safety.
When we post a tragedy similar to the ones you referenced, it is done to expand on the very foundation that safety takes precedence over any firearms related action.
Sadly, there will be folks like Plaxico Burris and others, that simply don't get it. Those that take for granted the immense responsibility that comes with being a firearms owner. These are the stories the anti-gun folks thrive upon, and an aspect we here always reiterate as the foundation that precedes all others when it comes to handling firearms.
Take care, and stay safe.
