This video convinced me Russia is using DEW weapons on American diplomats and officials

Why would the CIA cover this up as injured agents would be a budget winner to find out the Cuban (if Cuban and not ex-soviet) tech behind attacks? Unless CIA false flag to stop diplomacy and relaxing sanctions? Seems injuries occur around diplomatic activities (as with Trump Cuba and with Kamala Vietnam) with countries who want to improve economic relations with USA. No surprise if people injured are pro improving relations, especially if CIAagent having imput into agency policy and which they are now unable to participate in due to illness.
