Story appears to be that is what might work to stop them - have to catch entire sounder, not just some of them. Hunter that takes shots - kills two out of 14 - has sent other 12 running - to new areas - they do not re-group once spread by a scare like that - too smart - how they expand their turf - poor or sloppy shooters makes it worse, apparently. When a single sow can produce 24 or more in a year and shooter gets two - that is not controlling the population, at all. At most, might drive them fully nocturnal. Then what?
