He didn’t get shot over a bottle of water, he got shot because he pulled his own gun.
Oh, you're no fun anymore!
The only information in the report about the kid having a gun was just a statement by the store owners son that he saw a gun on the kid. That statment did not say the “kid pulled a gun”, only that a gun was seen, and only from a statment by the store owners son. Time will tell if more evidence comes out or if the son’s statment is contradicted by evidence.
