The word confronted means to stand in opposition in a hostile manner. An example of a sentence with this meaning would be: "Everyone dreaded the consequences if the the two nuclear armed nations confronted each other directly on the battlefield."
Confronted is also used with reference to something that is in one's way. For example, "Though her grades were excellent, there were several financial issues that she still had to confront before she could join college.”
Usually in legal terminology the word confronted is used when something is presented for acknowledgement or contradiction. For example, “He was confronted by the law enforcement agency with credit card records that showed he had bought the gun used in the murder.”
