The latest “ripped from the headlines” story on Law & Order: L.A.: The shooting in Arizona that left six people dead and 13 injured. The season finale, which started filming today, is about a female senator who is gunned down during a public event. A rep for the show is stressing that Law & Order is fiction (we’re still trying to process the news that Munch isn’t real), but we’re talking about a tragic crime here, not the marriage of two winsome Brits. Is it too soon for a TV dramatization?
