I realize these decisions are hard to make on the spot, but it's important to grab everybody and pull them out on the spot. As a teacher (or me in a previous life, as a manager --- also of adults), when you disagree very strongly with the ethics of actions of others, I found it both personally and team-wise rewarding to react decisively in front of my team so they'd get the message.<p>This applies to not only strange security, but harassment, unethical behavior, and other inappropriate actions.<p>Trust me from personal experience, you'll never regret it, and as you get older, the retelling will only get _more_ enjoyable, both for you and those who were there to see you blow up. On both sides, so long as you keep it professional.
