Poaching, yes, I would turn someone in. Don't think I care who.
When it comes to splitting hairs, I don't know. Example - the law for shooting times is a half hour before sunrise and half hour after. I was always told that basically if you could see the sights well enough to know for sure what you were shooting at, then it was light enough. If there was question as to whether or not you could clearly see the sights or the target, it was too dark. I have found this to generally be a pretty accurate gauge of time. I passed on a deer last year because I decided it was just too dark.
On the other hand I know people that look up the posted time of sunrise/sunset for that day and figure 30 minutes from that and will not shoot a minute too early or a minute later.
I guess for me if it violates either a major safety rule I'm not ok with it. If it gives an unfair advantage I'm not ok with it.
Do you drive 3 or 5 mph over the speed limit? If you catch yourself doing it do you go ask for a ticket? Where's the line? Just something to think about.
