Please note that I said SEE interference.

Mike,
If I am absolutely sure that I've just seen interference, yup, call it. But, before I call interference, I'm looking to see what my partner is doing. If my partner has a good look at this same play - right position and can see what needs to be seen and is looking at it - my split second or so delay is going to let my partner call it. And if my partner is looking right at it, chances are real good my partner is going to give a "safe" signal which sez "Yes, I saw that and it's nothing." My split second delay is going to avoid us having conflicting calls AND is allowing my partner to keep/have/whatever primary responsibility where my partner has primary responsibility.
