The CIA and NSA are agencies responsible for global monitoring, collection and analysis of data regarding foreign and domestic intelligence. In order to achieve these agencies are justified to spy upon Americans on various grounds. Terrorism activities form one of the proponents where these agencies are required to spy on Americans. There have been increased global terrorism activities. This permits that security and surveillance agencies such as CIA and NSA to monitor patterns of communication to identify possible threats (Martínez et al., 2020). In addition, a good number of terrorists are living in the country while they relay information to their colleagues before attacks. This requires that NSA and CIA spy on Americans through accessing their phone calls, texts, Facebook accounts and other avenues of communication in order to address these security challenges.
The Foreign Intelligence Surveillance Act (FISA) of 1947 regulates the various security agencies of the government on physical and electronic surveillance. CIA and NSA are justified to spy on Americans given that the information they seek to obtain is attributed to the safety of Americans. For instance, these agencies can undertake spying of specific individuals after perceiving that they might be involved in criminal activities such as child and women trafficking, drug trafficking and illegal selling of firearms (Coddington, 2017). This is achievable through collecting information from cellphones using high technology software. In addition, exploiting information through hacking of Facebook, Twitter accounts or any other source of information contained by the suspects is fostered. Therefore, it is essential to note that the United States Freedom Act has stipulated a number of provisions that lists civil liberties groups. NSA and CIA only spy on Americas that are a threat to national security.
