Well you can call it eradication or whatever,
think what a public hunting festival this could have been
if they would have opened it up to hunters,
all the fees people would have paid going toward game management,
the fun of hunting and resolving an overpopulstion etc.
When you supply the location, facilities, organizational logistics, and proper permits, arrange for sanitation and range safety, then you can have your public hunting festival. However, while the rest of us are waiting for you to make all that happen, the hog population is going to continue to grow and other people will be implementing their methods for dealing with the problem.
