There apparently isn't a unified Republican message on whether President Obama has introduced a big new tax through the Affordable Care Act.
Eric Fehrnstrom, a top aide to Mitt Romney, said Monday that the Republican presidential candidate's position is that the penalty under the new law — the one for people who can afford to buy health insurance, but don't — is not a tax.
The Supreme Court last week upheld the health care law's individual mandate on the grounds that it is a permissible tax, in a 5-4 opinion authored by Chief Justice John Roberts.

An interesting technological case has emerged from the Occupy Wall Street protests of last fall. At issue is whether prosectors can simply subpoena the tweets of Malcom Harris, one of about 700 protesters arrested last year while walking on the Brooklyn Bridge.
Manhattan Criminal Court Judge Matthew A. Sciarrino Jr. had already ruled on this once before saying Harris had no jurisdiction to challenge the subpoena because his tweets belonged to Twitter.
