Bravo!  But are you sure that the time and energy required to trap is necessary?  Can trapping be carried out as quickly and efficiently as will be required?  Perhaps instead of flushing all those narcotics from the opioid epidemic into injection wells, the drugs can be recycled into the ferals' water supply for a mass sleepover.  What could be more humane than being cradled in the arms of Morpheus for eternity?
