You didn’t set up a mob. This is what you described:
“So James called his friends and organised a campaign against Richard, sending letters to Richard’s employer, using Twitter and other social networks, demanding that Richard to be punished. Richard’s employer decided that they do not want negative publicity and decided to fire Richard.”
So how many people is this? 3? 5? 20?1,000?
You seem to think getting a mob together is really easy and that people are just helpless empty vessels waiting to be manipulated. How many people do you think it takes to get Richard fired?
