There is a little known USDA agency euphemistically known as Wildlife Services.
Their employees have one mission: kill our widlife using any means. Usually it's poison which causes a very painful death.
Perhaps some reflection of public outrage might convince Secretary Vilsack to eliminate this agency.
A picture of 11 cougar heads stacked neatly by the Wildlife Services employees can be seen at:
