] Flavia Carvalho recalls unlocking the door to her
] computer software store here Tuesday when she noticed how
] utterly alone she was on a commercial block that is
] usually bustling by 10 a.m. Everything was closed: the
] shoe boutique, the art gallery, the colossal supermarket
] on the corner.
]
] Then, with a tap on the shoulder, a young man appeared,
] seemingly from nowhere, with a message all the more
] chilling for its casual delivery: Shut down your shop for
] the day, or else.
]
] "I thought: Oh, no, not again," Carvalho said. "Another
] day without business. But what could I do? He told me
] that anyone who opened would be shot or burned."
