A Targeted Individual is someone that has been selected by the Deep State (usually FBI or CIA) to unwillingly participate in a government experimental torture program. This program is designed to break down the individual and "neutralize the person," using psychological, physical, and emotional stress. The ultimate goal of this program is to control the entire global population. Political activists and whistleblowers are two of the main targets. Family and spousal relationships are usually destroyed, as part of this torture.
