Research Brainstorming

After brainstorming for my research topic I thought it would be the most interesting if I focused on a social controversy. The 3 I came up with were gay marriage, the use or miss use of medical marijuana, and school shootings. I decided on going with school shootings because people don't realize it could happen at their school and I've been hearing about them happening at universities over the years. Now living on a college campus Ive given thought that it could happen here and can relate to any school student. Some possible questions I've raised were: Are school shootings more likely to happen at a large university or at a high school? Why have troubled kids decided to kill their classmates? was it a result of bullying? and finally Has there been an increase or decrease in school violence in United States? After I choose which question I want to further investigate I will definitely narrow the focus to a specific time, location, and maybe even school that has already had a shooting.
