What can trigger criminal offense

Crime-provoking acts. I wonder what provokes people from committing crimes. If you have noticed, news reports are all about assaults, murders, and ambushes on different parts of the world. What could have triggered them from doing such stupid offense? Yesterday I have seen another lawbreaking act on the television for around the world news, which is about a man who killed twelve innocent people inside a movie house. A tragic scene indeed! Although that happened in the States, still we should not be laidback when it comes to safety. Police officers must always be vigilant in seizing criminals. Thus, if you have observed that in other countries, military training has already been incorporated in their curriculum to ensure preparedness at all times. Not only in Asian countries, us military schools as well are watchful when it comes to all possibilities of terrorism. I just hope that everything will be under control, so that we will live peacefully and not in fear.
