GW's have such broad powers and the laws can be very complicated and are often only briefly summarized in whatever annual booklet a given state provides to the point that they can give you a pretty good hassle about any time that they want. As with any group of folks in positions of authority, there are always gonna be a few bad apples. I have no complaint about my single encounter with a GW and actually enjoyed hanging out and talking with him for about 15 minutes after he checked me.
