In his Talking Points Memo tonight, Bill O'Reilly said that a war is going on in American cities such as Baltimore, Chicago and New York City.

"While the grievance industry concentrates on police officers shooting black citizens, the real war is criminals shooting Americans," O'Reilly said. "Many of whom are innocent bystanders."

He pointed out that the month of May was the most violent month in more than 40 years in Baltimore. 

"43 homicides and non-fatal shooting incidents up 60 percent this year," O'Reilly said. "In Chicago, 47 Americans [were] killed in May alone ... The carnage in Chicago has been going on for years with no end in sight."

O'Reilly also said that the murder rate in New York City has increased 15 percent since Mayor Bill de Blasio ordered police officers to end their controversial stop-and-frisk tactics. 

"Cops are angry with de Blasio for not supporting them," O'Reilly said. "Therefore, low-level offenses such as double parking, aggressive begging and other so-called quality of life crimes [are] not being enforced."

O'Reilly noted that "Democrats run the show" in Baltimore, Chicago and New York City. 

"And their permissive attitudes toward public policy are the primary reason violence is up and social order is down," he stated. "Unless the nation somehow begins to understand that strict policing is necessary to protect lives, this violent trend will continue."
