How we love and cheer when a movie's wronged hero or heroine swears to catch the villain "red-handed" and actually manages the same! However, there's difference between reel and real life.
Perhaps an 'Angry Young Man' or 'Supergirl' can ensure the villains getting caught red-handed in real life too.
I feel if people knew that they were sure to be caught red-handed and heavily punished, then they would never attempt anything terrible. No untoward incident would have happened as no one would have dared to indulge in any wrong-activity.
