Why is it that someone who is trained as an intelligence officer and almost certainly knows how information system security / audit works often seems to make obvious mistakes in their attempt to defect to a foreign adversary? It seems odd that someone with this level of expertise would make obvious incriminating google searches and similarly send incriminating emails. Then again, we may only be learning of those who are (paradoxically) lacking in basic operational security.

Was this person perhaps hoping to get caught to raise awareness for their reports of corruption?
