Scrutiny is close, detailed inspection with a critical eye. Not a glance — a going-over.
The word usually arrives when somebody is being checked on: under scrutiny, public scrutiny, close scrutiny of the accounts. Parliamentary scrutiny is the formal business of examining what a government is up to. The phrase that does most work is bear scrutiny, because a claim that does not bear scrutiny falls apart the moment anybody looks properly. The verb is scrutinise, which means to look at something very hard indeed.
