Regarding the Dursleys choosing to punish Harry as being responsible for the strange events, and that being at odds with their desire to deny that the events are actually strange... I would like to point out that the Dursleys, however cartoonishly they are being portrayed, are still human, and therefore prone to logical inconsistencies. Look back at your own childhoods; can you honestly say, even in hindsight, that everything your parents did in raising you was logically consistent?
Around 39:00 into the podcast, the topic of Mrs. Figg's treatment of Harry is brought up, and someone asks why she doesn't treat Harry better. Arabella herself tells Harry why when she and Harry are taking the demented Dudley back to his home; she had to be sure that Harry wouldn't like coming to her house, or the Dursleys would stop sending him there.
"Why didn't you tell me you're a Squib?" Harry asked Mrs. Figg, panting with the effort to keep walking. All those times I came round your house -- why didn't you say anything?"
"Dumbledore's orders. I was to keep an eye on you but not say anything, you were too young. I'm sorry I gave you such a miserable time, but the Dursleys would never have let you come if they'd thought you enjoyed it."

It is not for the faint of heart.
How does the International Statute of Secrecy handle situations with Muggle-borns and their extended families finding out about the Wizarding world? For instance, how would it apply to James telling Vernon about his broom?
Can you provide the source for that?ASU Sun Devil Quidditch
