IMO if you want to own hots, you should at the very least be required to take the necessary steps to procure your own antivenom for the species you intend to work with. Relying on somebody else having it is irresponsible and incredibly selfish.
The herp community as a whole is against restrictive regulation, but this is one instance where some regulation be beneficial.
I am in favor of a realistic permitting system being put in place for venomous, and probably a similar yet separate permit for large constrictors.
I believe it would go a long way to protect ourselves from keepers like this. As well as the guy keeping a large Python in a 55 gallon aquarium with a blanket for a lid being held on by clothespins.
There needs to be something in place to separate us from the people who are so clearly doing it wrong.
