And the riots in Pittsburgh would make us all forget about the stupid cartoons.
I think Seattle is the city that has a more recent history of riots. The last "riot" of any note in Pittsburgh was in 1860 after Lincoln was elected and a staunchly Southern fellow named Floyd, who happened to be President Buchannan's Secretary of War, issued a midnight order to clean out the local Army arsenal and ship all the big guns and ammo down south.
The local folks took "offense" to that order and made sure it wasn't carried out.
Let's put it this way. As a rough estimate without checking the records, the City of Seattle has at the minimum of 15 years to go before they can experience as many NFL playoff losses as the the City of Pittsburgh has experienced and I sure don't recall any "riots" in Pittsburgh after any of those losses. People did pretty much the same thing after those losses as they did on Monday morning this week. They got up and went to work.
