Arrogance

"Kate and I got the respone we wanted after speaking to the Portuguese ploice today.
We are assured that no criticism of our actions on the night Madeline disappeared was intended."

Doesn't that statement (which appeared on the McCann's blog) appear a little arrogant?
I wish I could get the response I wanted whenever I contacted the Police.
Unfortunately I looked after my children in a responsible manner and don't have nearly a milioin quid to jaunt around Europe as I feel like it with an army of Media Yes men to coordinate my daily life.

Could that be the cause of their sheer arrogance in proclaiming that abandoning their children shouldn't reflect badly on them?
Is their blog there to protect them from any criticism or is it really just to find Madeline?
