On page 12:
"There was no improper use of an unmanned aerial vehicle. It appears to have had no bearing on these charges being contested here."
CBP has used drones with FAA approval within the US since 2006; which does not included any use prior to 2006 which remains classified.
Only a fool would be evaluating the first case to judge whether the whole idea is valid.
