Before our opponents get all uppity, it is in China:
Three policemen were killed and six people wounded in a shootout with a pair of murder suspects in Ti’an city in eastern China a news report said Wednesday.
Gun crime is relatively rare in China owing to strict gun control laws in the communist state, which outlaw the manufacture, ownership, transport, renting or sale of guns and ammunition by private individuals or institutions.
I think gun crime is relatively rare in China because it’s a police state, and not because of the gun control. I doubt they compile realistic crime statistics anyway. The gun in question was a home made pistol and shotgun. This was a rampage shooter too, it looks like.
