Yes, just from conversations.
The first thing is that there are plenty of signs about biosecurity on a chicken farm. They're there. They're loud. They're right in front of you at the driveway. What's happening here? Why are these people ignoring the signs? Most people obey signs.
Then, from what I understand, it's to call the police, and then the police don't know what to do, really. I think that's probably the answer to your question right there.
