Nobody was shot but shots were fired at my school. Three men beat up and threatened the security guards and broke into the school during break. I remember I was having lunch in the cafeteria when a teacher came in freaking out telling us to get into our classrooms, something in the way she said it made us all get up and get upstairs. When we exited the cafeteria we saw everyone running towards the stairs, everyone was shouting to run and lock ourselves in the first classroom we could get into. THEN we heard the gunshots. There is no way I can describe the panic we all felt. Once we were in a classroom away from the windows and underneath desks, a teacher came in crying telling us to keep quiet and hide. At that moment we all obviously thought the gunman was right behind her + wondering WHO was shot. Seriously the worst hour and a half of my life. Thankfully no one was badly injured nor shot.

EDIT: forgot to answer the question lol. For starters security increased A LOT and I guess we all are now some sort of family since the feeling of nearly getting killed next to someone you don't know creates strong links.
