Obama expected to obey the law

Duhbya's White House blithely ignored the Presidential Records Act, but Obama will have to give up his BlackBerry to comply:

But before he arrives at the White House, he will probably be forced to sign off. In addition to concerns about e-mail security, he faces the Presidential Records Act, which puts his correspondence in the official record and ultimately up for public review, and the threat of subpoenas.

I don't buy it. As long as his friends know that their correspondence is going to be an open book in five to twelve years after the end of the administration or could be subpoenaed, and as long as Obama refrains from classified discussions, the only reason for him to give up his back channel is that it's a time sink. He seems disciplined enough to me to handle that.

Can we please at least pretend that law can work in ways that make sense?
