Could you please explain the difference in meaning in the following sentences.
- The detectives have interviewed two people this week.
- The detectives are interviewing two people this week.
I think the first sentence implies that the detectives interviewed two people during unfinished period of time (it might be in the beginning or the end of the week). That is, they interviewed them and the process of interviewing other people will continue. The second implies that the detectives are still in the process of interviewing the two people during the week.
Is my understanding correct?
