Can a business claim "no duty of care " for government property stolen on its premises?

I JUST NEED TO KNOW THAT IF THE CONTENT OF MY FLASH DRIVES WHICH WERE BUSINESS DOCUMENTS FOR THE COMPANY I REGISTERED WITH THE U.S . CENSUS WHICH MAKES THEM GOVERNMENT PROPERTY ARE DUE SPECIAL CONSIDERATIONS AND THAT MACY'S DEPARTMENT STORE HAD A "DUTY OF CARE TO CO-OPERATE MORE FULLY IN THE INVESTIGATION AND THAT THE GOVERNMENT HAD INTEREST IN THE RESOLUTION OF THE MATTER MACY'S DID NOT ALLOW ME TO VIEW THE VIDEO SURVIELLANCE FILM THAT COULD HAVE REVEALED THIER EMPLOYEE CULPRITS (CLEANING PERSONNEL)OF THE RESTROOM WHERE I LEFT MY BAG. HOWEVER A JUDGE MADE A RULING SAYING THAT MACY'S HAD" NO DUTY OF CARE IN THE MATTER" I DON'T BELIEVE THIS IS TRUE SINCE MY COMPANY "AMERICAN ECONOMIC RECOVERY PROJECT FOUNDATION INTL" AND THAT IF THEY PLEDGED ALLEGIANCE TO THE FLAG OF AMERICA THEN THEY HAD A DUTY OF CARE FOR AN AMERICAN AND GOVERNMENT OWNED COMPANY
