I've seen that reported too, but without a source I can verify, I'm just assuming it's a fabrication to achieve a narrative interesting to a category of readers ("why haven't they arrested him when he was unlawfully in possession of a handgun! this smells like George Soros!") Gotta get those clicks to afford the chicks!I've seen it reported that he was arrested for burglary, but I've never seen it reported that he was convicted of it. Arrests do not show up on CCAP (Wisconsin's online court access system). You'd have to be able to access his criminal history to find out if he were arrested.
It's time to roll out a journalistic standard of including source footnotes for *everything* so readers can cross-verify. That might actually be in interesting start-up, a mouseover application or plug-in assisting a reader in analyzing a news story.
