I think the Capitol is being very ignorant, cowardly and nervous. They are being ignorant and cowardly because they are destroying anything (Big or small) that may start an uprising. They don’t take one second to consider it might be wrong. For instance one time, Katniss was talking about Rue (One of her allies) and one person from the district whistled Rue’s tune to show that he was a friend of Katniss. Then a bunch of peacekeepers came and killed under the Capitols orders.
They are nervous because if there is another uprising then there will be chaos and the Capitol will probably be destroyed and they won’t have power any more.
Those reasons are why I think the Capitol is being Ignorant and Stupid.
