Power
It may come as a surprise, but hunter/trappers actually have some power because of their specialized knowledge. Let's say you have trouble with a possum or raccoon that decides you have the best garbage can in town. Who you gonna call?
Unless you want to get licensed, go spend a few hundred bucks on a gun, and sit up half the night waiting for some wayward varmint to show up, a hunter/trapper is your best bet. They have the knowledge and equipment to capture, take away, and safely release the unwanted guest to a better location. All you have to do is write a check. Sounds like a no-brainer to us.
Knowledge is power, and hunter/trappers are all about knowing the local wildlife: their habits, their diets, and when they pose a danger to humans. What may not strike the average person as dangerous can be under the right circumstances; you know what they say about getting between a mother and her baby.
Professional hunter/trappers may be called on to teach classes to new hunters who need to understand the dangers before going out into the wild for an adventure.
A hunter/trapper's power is also found in their knowledge of which animals belong where and their ability to relocate them when they overstep their bounds. For example, the alligator population has exploded in the southeastern U.S. due to plentiful waterways and restrictions on killing 'gators.
That's cool and all, but when the scaly dudes wander into golf course lakes and creeks that run through neighborhoods, things have the potential to get ugly. Local hunter/trappers are the ones with the knowledge and skills to solve the problem. Better them than us.
