I'm with you Ballin, not really sure where i Fit in this argument since i love dogs as well?
On a personal level though, i think the only way to really control these problems, without full on banning any species of dog would be to have an gov't agency setup where people who want to own certain more aggressive species of dogs need to prove they are training their dogs properly, and socializing them to try and avoid these problems, with possible yearly or bi-yearly checkups + licensing .
Also, having these types of dogs locked up safely in ones property is another important issue, since some of them do have immense agility and are able to scale 6' + fences and walls quite easily
