That might yet turn out to be true, but as of now, reports have only stated that Ouslon made some statement to the affect that he believed Reeves had done so.
I wasn't there. I don't know what happened.
What we are entirely certain of, is that Reeves shot and killed Oulson.
And yes, it looks very much like a crazed gun owner escalated an argument over possibly rude public behavior into murder.
Reeves either had the gun, or more likely, went out to his car and brought the gun back into the theater to shoot Oulson.
I would deem that proof positive of premeditation, and lethal intent.
Looks can be deceiving. It is Florida and a lot of people carry. He may have gone to use the restroom for all we know. I remember another story about a neighborhood watch captain who gunned down a young teenager for nothing more than the color of his skin. It was all very believable when that story was first reported, a wanna-be cop just itching to shoot someone (guns have that effect on people you know) murdering an innocent kid in cold blood. I’m not so trusting of news reporting anymore.
Pasco Co. Sheriff Chris Nocco specifically described the scenario wherein Reeves left his seat to complain to theater staff. When he returned, Oulson was giving Reeves lip about tattling to management.
