James O'Keefe update

Patterico is blogging over at Hot Air. He compares several recent cases and makes a decision about O'Keefe, the conservative journalist who exposed ACORN:

Steward was peddling lies. The Black Panthers were spreading fear. James O’Keefe was searching for the truth.

Only one of these cases is being prosecuted.

Maybe James O’Keefe did enter a federal building under false pretenses. Maybe.

But doesn’t every Congressperson do that every day?
