I am from a small town in texas and i went to a volunteer event at a old middle school for 10 people to act of scenerios for a school shooting for out police department to get a feel of what we need to do if that happens and they placed tourniquets on me and made me scream for help and etc
I really want my essay to be about how i did that and it can be a little bit exaggerated if needed but i want it to be about how doing that shaped how i view our police department and how it will help in the future and i kinda want to get in the controversy of school shootings
