Re: Persian Gulf naval incident:
I hope it is SOP that when the guns are readied to fire, that someone is filming and recording the whole thing, including loudspeaker and radio traffic.. This could be automated cheaply, but defense contractors would surely charge a fortune.
For warnig purposes, they could use lasers in the eyes of the approaching boat operators (about $30 from radio Shack) If this is ignored, stronger lasers could blind them. It is more humane than shelling them as a next step.
Come to think of it, it would not be a bad idea to have a "black box" that keeps a record of the last few hours of all operational and situational data.
