Why Foreign police and security agencies wont trust Indian elite force and state police ?

We all know that Global Economic Summit is going to be held in Hyderabad for two days on 28th and 29th of this month and daughter of American President Ivanka Trump is the chief attraction. The American security agencies have already taken position of places she is going to visit and there is no room for Indian elite police or state special police. When the local police services are not solicited how the foreign police know about the security cordon of state police which pressed into service in advance. American police has the right to guard their citizen but not at the cost of demeaning our elite forces and police.
