I told you that you weren't gonna like it.

Whoa.......it's not a matter of liking or not liking something at all. I'm here to learn, and I can't do that until I understand completely where you're coming from.

Are you saying that if you have an obvious palm/carry in the backcourt, with no defensive pressure, you would call the violation?

Could you then please explain exactly what the difference is between what is "obvious" and what is "not obvious" is when it comes to a palm/carry? I just want to know what criteria that one should use to either call the violation or ignore the violation....bearing in mind that both are violations no matter what.
