  • some people may want to hurt attendee, because they are disappointed with him.
  • some people may just be crazy and want to hurt someone in front of many people.
  • spies may want to get access to some important documents.
• Countermeasures:
  • set up cameras that cover every corner of the place, and hire some people to watch the CCTV and patrol around the place. This may need a lot of money to hire professional security guards, but this helps prevent lots of threats.
  • hire people to oversee food preparing, food making and every procedure. This may need a lot of money to hire professional security guards, but this helps prevent lots of threats.
  • security check for all people entering the place. This may slow the speed of people entering the place. But it can prevent weapons from entering the place.

It costs lot of money and passenger's time, but it can prevent hazardous stuffs and weapons to be onboard, which vastly reduces threats.
  • train stuff to be cautious on every process of preparing foods, to prevent any possible of the food getting poisoned. Also, secure surveillance cameras should be set up to monitor the working area to ensure there are nothing abnormal happened.
