Do you really think that that will solve anything? The person who made this mistake has basically been punished enough today. All the protocols dealing with the escape worked perfectly fine and it was dealt with professionally. You can train endlessly, but human error can and will always happen. Protocols can only hope to minimize human error and given that this was the first large mammal escape (as far as I know), the protocols work.
I agree that the situation was dealt with the best way possible, although with a very unfortunate and undesirable, even if expectable outcome.
I also agree that the responsible person will already have been punished quite severely through what has happened, but I still find this person can no longer, nor can ever again be trusted to function correctly within Planckendael or within any dangerous animal enterprise.
In fact this was however not the first large mammal or predator escape in Planckendael. In 2005 two cheetahs walked out of their housing because a gate was wrongly left open. The two animals were back in their enclosure within half an hour without consequences.
I assume it's possible something similar happened today, although with sadly much more serious consequences.
In any case, I think the protocols should be thoroughly investigated and evaluated. I at this moment, despite agreeing that the lioness situation was dealt with well, feel I cannot trust Planckendael's protocols to be sufficient to ensure visitor safety and if I so desired I would not dare to visit the park at the current time.
I also still believe that the quite possibly irrevocable and unrepairable damage to Planckendael's reputation and image and the amount of ammunition this incident will give animal rights activists and zoo opponents, and the possibly innumerable resulting damage, warrant strong action against the keeper and against Planckendael.
Everybody makes mistakes (or are you perfect?

) so we'd be hypocrites to be so militant before we know the full facts when someone slips up. Doctor's who kill patients in error don't typically lose their jobs because people realise they were trying their best. If you're never going to Planckendael again because of one mistake does that mean that you'd similarly boycott any doctor that had made an error -hope you don't get ill.
So you'd basically bankrupt the, possibly otherwise exemplary, keeper for a single mistake? No one but the very rich would ever want to risk being a keeper if one slip up could bankrupt you (it'd be like working with a Sword of Damocles" above your head).
Of course everyone makes mistakes. But not all mistakes are the same. And I believe that mistakes that put the lives of animals or people in jeopardy cannot be tolerated and should be dealt with strongly.
As far as the comparison with doctors and medical errors go: I think there is a great difference between doctors trying everything but failing to save a patient, doctors making non-deliberate errors in the stressful situations that can occur in medicine or having undesired side-effects to treatments and doctors deliberately or through negligence making preventable medical errors that lead to the death, serious injury or disability of a person. The latter category of doctors I most certainly do not want in the medical profession and I find are not dealt with harshly enough in society today.
There are different levels of slip-ups. Slip-ups that put the safety and lives of people, especially visitors, at risk cannot in my opinion be tolerated.
Keepers should be allowed to make mistakes, but they cannot be allowed to put people's lives at risk. That kind of mistakes should be dealt with in the most severe way: ejection from the keeper profession for life.
At this point I do not feel like I can trust Planckendael or its employees to ensure the safety and welfare of animals, employees and visitors. The mistake that happened today is so severe that I believe it warrants at least a temporary boycott.
Mistakes happen in all walks of life. No reason to punish the zoo, or the individual, OR to be nasty about it.
I admit I could have been more than a little less harsh about it, but I still believe that both the park and the responsible employee should face serious consequences for this incident.
