Some people in New York are wondering whether the presence of police officers toting machine guns through the city's subway tunnels is really a necessary response to the subway bombings in Moscow on Monday.
"I think it's ridiculous," Torey Deprisest, a tourist from Ohio, told the New York Post. "The attack happened in a different country and had nothing to do with Americans. I'd be nervous seeing cops with machine guns on the train. It makes people afraid when they don't need to be."
