I believe there are some emergency exits that open either way, but the cabin doors require inward motion before going out. Impossible when pressurized at altitude. Even with just 1psi pressure differential (about 3000ft altitude difference between in and out) you'd be looking at about 4500lbs...
And yes, if we believed everything Donna Bell of Visalia Calif. tells, and the Sacramento Bee has the audacity to print, we'd surely all be dead.
