just partying. Not a protest, not a demonstration, just a party.
Mobs are a dangerous phenomena, be it a protest, college revelry, or Trevon supporters, or patriotic revolutionaries. There are always a few unbalanced people therin who are seeking the cover of numbers to engage in vandalism or violence. There are sometimes leaders who encourage mob action for perceived political gains.
Parents should always teach their children to almost always avoid the excitement of a large crowd, except at sporting/music events, etc.
It’s not a party until two people get stabbed.
