When someone repeatedly feeds chicken to a croc, its pea size brain starts associating people with food. That's the problem, and it is beyond legal or illegal, stupid or not stupid.
We should leave them alone, or have the smart people from Belize Zoo be consultants on how to create a lagoon croc zoo under controlled management and let the kids sell "I met the croc" t-shirts, souvenirs and ice cream instead of risking their own and others' limbs on an every day basis.
