Eugene Robinson is very aggrieved about the new Arizona law:
Legal immigrants will be required to carry papers proving that they have a right to be in the United States.
So aggrieved, in fact, that he's apparently mixing up his tenses. It is already federal law for legal immigrants / visitors to carry their green cards and/or other relevant immigration information with them at all times. It's been that way for years. [UPDATE: See also here.]
Mr. Robinson, if you don't even know the basics of what is legally required and what is not, please keep out of the conversation until you've caught up with the rest of us. I ask this as somebody who favors immigration reform: you're making my life more difficult.
So stop that.
