I agree the statistics say it is safer than ever on a per-person basis, however, I think the overall complacency factor in this sport continues to grow. I think the reason there haven't been more incidents is the continuous evolution and improvement of the gear. I keep hearing stories of rigging issues that are found and I can't help but shake my head in amazement that nothing happened as a result.
I know there are some people who have a tendency to see what they can "get away with" and once that works, push it a little further, and repeat. Although this kind of thing has been going on in the sport forever, I think with the increased competition and harsh economic realities of running a DZ these days, it is increasing. Maybe my perception is skewed by what I keep hearing from near me, but I think it is only a matter of time before we see even more incidents that can be traced back to what will ultimately be deemed negligent behavior and I'm sure lawyers will be making money.... :-(
