Where are you from?
No offense, but I honestly could not understand more than half of the things you were trying to say. It was difficult to comprehend...
But about the zoo thing (which was the only part I was able to fully understand). A lot of people here and in our community are more knowledgeable than some zoo keepers and/or have more reptiles than most zoo collections. Just something to think about. I'm not saying everyone is an expert, but some of these keepers have been handling these reptiles for 10, 20, 30, 40+ years. Yes, large constrictors have the potential to be dangerous. But you're preaching about a subject you have very little knowledge on.
