Hunting drive-by killers on patrol in Baghdad

By Ross Colvin
BAGHDAD (Reuters) - "Take cover!" yelled Captain Ryan Nystrom as gunshots rang out.
The leader of the 14th U.S. Cavalry "Crazy Horse" platoon and his men crouched behind a low wall, trying to figure out where the two "pop pop" sounds had come from. A minute later, they heard the low boom of an explosion somewhere nearby.
They were hunting two cars that residents of the southern Baghdad district of al-Hadar had told them were responsible for a series of fatal drive-by shootings in the past few days.
