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.
