What is a potential benefit and potential negative impact of the work of the DNI?

The Director of National Intelligence's work involves coordinating the many intelligence's agencies in charge of security and espionage in our country.

Explanation:

Some of these have had historically conflicting objectives (the DEA efforts against drug trafficking conflicted with the CIA strategy to finance counter communism movements) and the operate with high degree of secrecy.

On the positive side, their work protects the life and safety of Americans from unknown threats.

On the negative side, the secrecy they operate makes them difficult to be held accountable and they operate in the margins of people's rights. There's a trade off between Security and Liberty, and sometimes the threats to security do not seem to justify the cutback on liberties.
