Exactly. I can't think of anything more humane, other than maybe nitrous oxide or nitrogen, than slowly pumping in CO2 while it's feasting on some delicious strawberries and mango slices. Once it was knocked out I would slowly increase the gas until I was 100% that the job was done. Doesn't the Humane Society say that that is the only humane way to euthanize rodents? I know that raccoons are not rodents, and being larger it would take longer, but I would think that taking my time and slowly gassing it would be about as humane as possible in that situation. I don't really have a problem with a bullet to the head, but he just seemed awfully eager to pop a cap in that 'coon. It was kind of scary thinking that a lot more cops could be just as trigger happy while they're out there every day.
