Answer:
It is true that investigative journalism is invasion of privacy but only in one context.
Explanation:
The purpose of investigative journals is to root out the cause of criminal and unjust rulings along with corrupt activities that have taken place on account of public trust. Where on one hand these journals help in making the constitutions better for the public, on the other hand they tend to expose the questionable acts and the subjects involved in them.
This comes in the jurisdiction of invasion of privacy of those people who would not have brought the details of their acts otherwise if it were not for these journals.
