Ken Woods: You ask how letting a dog run in traffic is different that letting a dog run free. As it happens, I have the answer. Roads, cars, freeways, and traffic are a part of life, a necessity. You drive, I drive. We pretty much have to. But we don't have to trap. You trappers make the choice. 

You lay out your sets and my family has to tread very lightly,  but we don't know where to tread (wait - let me beat you to it: tread on the trail with a leashed dog!) Where are there NO traps? No-one but you knows and you aren't required to tell. You aren't required to put ID on your sets either. You sneak into the woods, hide your weapons and sneak out and if any one is hurt, well, they shouldn't have gotten in the way. Its the victim's fault.
