I wish people would stop conflating "keeping" with "transporting [across state lines]".
The person who started this threat specifically referred to non-native ants. Getting those by whatever legal or illegal method usually requires transporting them across state lines or even country borders (because if it didn't they'd be native by definition).
Sure, you can draw the line between native and non-native at city borders or county lines (which works for some species) but usually that's clearly not what people mean when they talk about non-native animals.
This is exactly what I'm talking about. Nobody is suggesting the ants were or were not illegally transported into the State they are in. Just because someone has them, does not mean they did anything illegal. Has it ever occurred to you that someone else may have illegally transported them into the State, and then sold them to someone else? This is why people need to stop conflating those two words.
One thing I wish is that he'd speak up and say which is which. If he got them from someone in state or he did it himself because now he's really quiet about this.
