Unethical Shooter Shoots at Boars

From a Moving Boat

This video from out in the wild internet shows a person blasting away at an entire group of boars with a pistol from a moving boat.
Even with the problem of wild hogs and boars here in the U.S., there are better ways to rid of the them.
This is just crazy on so many levels, starting with the fact that one guy hands his ‘buddy’ a loaded handgun, and then the shooter unloads on the animals. They all looking like they were on a joy ride than on a hunt.

This video was purportedly taken somewhere in South America. This is one of those video that gives the anti-hunters ammo to fire at us hunters.
I think most hunters would have set up at a likely spot for those boars to come out from the swim then blast away. What about the waste of all that meat?
What do you all think, would you do this?
