Wisconsin's Governor Walker "thought about" planting troublemakers among the protesters in Madison

The most important part in the phone call was where Walker said this (“because we thought about that”):

Koch: We’ll back you any way we can. What we were thinking about the crowd was, uh, was planting some troublemakers.

Walker: You know, well, the only problem with that —because we thought about that. The problem—the, my only gut reaction to that is right now the lawmakers I’ve talked to have just completely had it with them, the public is not really fond of this…[explains that planting troublemakers may not work.] My only fear would be if there’s a ruckus caused is that maybe the governor has to settle to solve all these problems…[something about '60s liberals.]…Let ‘em protest all they want…Sooner or later the media stops finding it interesting.
