Lt. Don Hutson said, "They both got out of the vehicle. They were both armed with handguns ... words were exchanged, there was a verbal altercation, and unfortunately Mr. Campos, who is the father of the young lady, fired two rounds, possibly three rounds, at Mr. Serbek."
The question is, what was said verbally, and what sorts of body language was involved? Can Mr. Campos plausibly claim that Mr. Serbeck's behavior put him in fear of his life?
This whole incident sounds like a series of mistakes, each of which escalated the situation. I can't absolve the Neighborhood Watch guys of their role in making this happen.
