How do we identify serial killers prior?

Since we are examining serial killers, I would like you to conduct a little research. The incident that has happened in Las Vegas and Texas has left us as a society searching for answers. How do we identify these offenders prior? Was there something we as a society could do to prevent this from happening again? Make new laws? Enforce old laws? The questions go on and on. This week I would like you to: 1) Pick an incident – Florida School Shooting, California Shooting, Las Vegas shooting etc… 2) Examine the offender 3) Was there a flaw in the system that could have prevented the tragedy from happening? 4) What would be a good first step? The paper should be 2-3 pages (double spaced, 12 font, Times New Roman) The paper is due on Sunday (Midnight) This paper should have at least 3 sources cited and a bibliography at the end.
