You are the responding officer to a shots fired call at a local mall. As you approach the mall, a muffled boom radiates from inside the mall entrance. Dispatch reports that mall security has suffered injuries from some form of explosive. Dispatch is not able to tell you the location of the bomb, type of bomb, or type of detonation.

Keeping officer safety in mind, how should you approach the scene? What dangers should you look for as you approach the scene? What do you believe are your justifiable decisions? Why, or why not?
