Likely because falconers want funding just as much as drone builders. But there might be more: having a heavy hunter-seeker drone over a crowd would be nearly as bad as having the occasional rogue drone there. Birds, with their amazingly low mechanical failure rate might be the preferable way of keeping reasonable people reasonable. Sensitive parts of the sky need to be kept clear of non-malicious, but nonetheless rogue drones not only because of accident risk, but also to get a clear threat indication from the malicious ones. "Probably just some kid who ran out of things to film with their gopro" is not very helpful when assessing the relative risks of a violent takedown over a crowd.
