Should external auditors be responsible for fraud detection?

Question

I am writing a research regarding audit expectation gap: the role of external auditors' for fraud detection. There has been some confusion or misunderstandings between what auditors'think they should do and what public think they (auditors) should have been doing. I need to get publiç's (users of financial statements) opinion on what they think of external auditors' role for fraud detection (should they be responsible or should they not?)

Answer 1

External auditors are the last line of defense for shareholders. But they can only look at what is prepared by the company finance people. External auditors can agree or disagree on how certain accounts are handled by the in-house accountants. But the overall control of what information is made available or hidden comes from inhouse.

Answer 2

We expect our external auditors to point out potentially damaging incidents (fraud), so yes, that's what we pay them for.

Answer 3

that's what they do and look for security weaknesses. You can't rely on internal auditor because they're part of the company no matter how independently they act
