LAS VEGAS (Reuters) - An armed man and woman shouting about a "revolution" opened fire and killed two Las Vegas policemen who were eating lunch in a pizza parlor on Sunday, then fatally shot a civilian in a nearby Wal-Mart store before killing themselves, police said.

The two uniformed patrol officers, later identified as Alyn Beck, 42, and Igor Soldo, 32 - both described as family men - were ambushed without provocation shortly before 11:30 a.m. local time inside a CiCi's Pizza shop, authorities said.
