nobody is up and beyond the law when it comes to poaching big game.
They got what they deserved for doing wrong. If they got caught doing this, most likely they have done it before, except this time they got nabbed.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
