Why are we buying Harper's family passports?

Now the amount is small and you may be asking why I'm even brining this up. It comes down to principle and accountability. Harper ran on a platform of accountability and not having a sense of entitlement. This shows that Harper thinks he's entitled to spend tax dollars on his family, who no doubt get to fly free with Harper as well, and despite publishing this information (something started by the previous, Liberal government) doesn't give a whit about if any of us find out. If Harper was truly principled, he'd have payed for his families passports, like the rest of us would have to.
It's also interesting that his family's passports cost the taxpayer at least $28 per person more than what the passport office charges. One has to wonder where that money ended up.
