And building that culture isn't going to happen if people take the stance that a TO/Judge's responsibility isn't pro-actively catching players violating rules during the games. Or if people act as if it isn't in the games interest to have others pointing out blatant rules violations like this....building a culture where it's okay to call the TO over even for "minor infractions".
Judges aren't going to catch everything, but they are there to catch things. Not just sit and look pretty, though I am great at that.
I'm not at all saying judges shouldn't be proactive--just that players bear a substantial amount of responsibility for acting on rules infractions, and we need to break players of the idea that calling a TO is a drastic action.
