I'm always amazed at how totally oblivious people are to the laws that regulate just about everything but especially pets. I'm sure they think "What could possibly happen." Then, I get reminded how these same individuals are the first ones to intentionally dump unwanted animals into the environment for who knows what reason. Others think that flushing dead or dieing animals down the toilet/drain is an acceptable way of disposing of them.
This doesn't even take into account the number of animals that manage somehow to escape into the wild even from dedicated hobbyists doing their best to avoid such mishaps.
Or, maybe it's just that these people are so eager to own the high quality critters you sell that they're willing to take the chance. I am constantly impressed by how nice the animals are that I have raised from the batch of eggs you sent me - including the one that survived a long, hot summer in my very small outdoor pond where the temps soared over 85 degrees F before I abandoned all hope and stopped checking. This one, to my surprise and great delight, was the one GFP leucistic that I didn't have among the group that I painstakingly maintained in proper quarters indoors.
