Intimidation is the use of force or superior power to discourage people from certain activities or thoughts, or to enforce other activities or thoughts against their will. Intimidation may be physical or psychological and may relate to a wide range of situations. It induces fear, apathy and alienation, reinforces barriers to progress and facilitates exploitation.
Terrorizing is threatening to commit any crime of violence or dangerous act or falsely informing another that a dangerous situation exists with the intent of keeping another person in sustained fear, causing evacuation of a building, facility or transportation means, or causing serious other public inconvenience. This includes phone and mail threats as well as bomb scares.
Any excuse will serve a tyrant (Aesop, The Wolf and the Lamb).
A threat can be just or unjust, good or bad, depending upon whether the threatened retaliatory measure is morally justifiable. The sanction normally attached to positive law is, in effect, a threat of punishment to be inflicted upon its transgressors. To threaten punishment may therefore be reasonable and virtuous, and a parent, teacher, or a custodian of the law, would fail in his duty if he neglected in some circumstances to threaten punishment. Prudence and care for the society and the individual to be threatened must dictate the norms to be observed in making justifiable threats.
