Daley defends police efforts to stem violence

In the wake of a bloody July 4th weekend, Chicago Mayor Richard Daley is defending the efforts of the city's police department to reduce violence.

Daley said Tuesday, long holiday weekends are usually difficult for police. He added that concentration of police at the Taste of Chicago was not behind the lawlessness that erupted elsewhere in the city.

Eleven people were killed and at least 30 others were wounded in shootings and stabbings during the holiday weekend. According to authorities, it was among the city's deadliest weekends in recent years.

According to police, some of the slayings appeared to be gang-related, while others may have resulted from domestic disputes. Many of the victims had criminal records.

Daley said the violence was a reminder the city must do everything it can to fight gangs, guns and drugs.
