University of Arizona and Tucson Police Department officers advise using the "Run, Hide, Fight" method if involved with an active shooter situation.
They say if you can, run as far away and call 9-1-1.
If you are unable to run away, they say hide.
U of A's Officer Hernandez says to make yourself a small target, lock and barricade the doors, and step away from the windows.
However, if the shooter gets in the room, they say fight and make a lot of noise to distract the suspect.
"These people have a minute decision they are going to go hurt somebody," said Officer Hernandez. "We want people to understand that making noise, using anything you have on your laptop, a cell phone, anything that can distract that person his or her frame of thought to get out of the room and an exit or engage with them."
TPD says the most important thing to remember is to be aware of your surroundings.

"Pay attention to what's going on in the surroundings around you, listen if you hear a gunshot, listen if you hear directions from people watch the direction of where people are going," said Lt. Greg Mammana.
They say although this is a rare type of incident, it is good to know how to prepare yourself.
