English to Bulgarian Social Sciences Idioms / Maxims / Sayings

The following text is an edited extract from an article by London-based journalist Roger Cohen published in The New York Times and discusses the attitude to risk in the UK:

"The balance between personal freedom and responsibility and government oversight has become seriously skewed throughout the West over the past decade. Sometimes post-9/11 security is invoked, sometimes health, always safety: the result is less initiative."

Как бихте превели "invoke"? Значенията призовавам, зова; моля, умолявам; търся (закрилата на закона) някак не ми звучат съвсем добре. Вие как мислите, колеги? Някакви по-творчески предложения?

Благодаря предварително.
