People writing the name of their murderer in blood on the floor is a murder-mystery staple; it is not real life.
In real life you're in shock and what you do is completely disconnected from what you think you would do. The "watch people die" video collections show that, someone can be obviously dying (massive gunshot wounds, etc) and they carry on like nothing happened until they fall over dead.
I don't think you ever been shot at, had you? I had, and being in shock first thing I did when called 911 was shouting the name of perpetrator for close to a minute, before I realized they already know who may have killed me, and now its actually time to tell them what's happening with me.
Again, it doesn't seem normal to say "someone shot me", if you know WHO shot you.
