You are still operating on an empty tank. The kid was the who started the engagement.
You’re the one operating from a vacuum — the cop was in his SUV cruiser.
So, I'd say that it's a lie...and it was the only thing he could think of saying.
Any clues why the kid ran?? After being shot. I'm guessing...but I'll bet that it was that first shot that "became" fatal from his own blood rushing as he tried to run.
