The fun part is that these cameras are not owned, operated or property of your local jurisdiction. They are hardware/software as a service. IANAL, but I think Flock would have to sue you.

I have not personally de-flocked anything, but my local area doesn’t have any that aren’t tied to a business parking lot.

If some show up, I can’t imagine a 5 minute walk with a hat, face mask and a can of spraypaint wouldn’t be sufficient to disable one without risk. Might need a stool.
