Interesting comments by the "expert"
When your heart beats get to around 120 Beats per minute and the adrenaline is flowing and the body goes into the flight or fight mode the first thing your body will do is switch you to tunnel vision and I guarantee you that you will not see the dot nor will you have the presence of mind to do so.
120 beats per minute (hormonal) causes tunnel vision?

If the author had really read Grossman and other studies of the physiological aspects of deadly force encounters, he would know that as the heart rate accelerates past 132 bpm, you lose the ability to focus on close objects. Combine this with the fact that your attention will, naturally, be focused on the threat, and you'll find that point shooting skills are the best means of surviving the situation.
And we see that the OP expert had suggested reading Grossman and to verify the information.
I have talked to too many people that have been in that situation including myself and all the stories are the same. Please don’t take my word for it but do some research for yourself. Read books by the experts. One to start with is ON COMBAT by Grossman, then go on from there.
Okay, did the research. He is wrong.
Interestingly, Grossman in
On Combat says that the optimal heartrate for fighting is 115-145 BPM and that you get optimal performance for complex motor skills, visual reaction, and cognitive reation. No tunnel vision. No Presbyopia. Such vision problems are more likely encountered at much higher heart rates, around 175 BPM. (see

I have always said that if I ever have to use my hand gun I hope the other person is using a Laser. I am not saying there is not a place for the laser as there well may be but not in this case. Technology cannot substitute for expertise.
Technology cannot substitute for experience? Strangely, proponents for firearms-based self defense note repeatedly that technology often does an excellent job of substituting for experience when as folks with little fight experience and often exceedingly little gun experience manage to use firearms (technology) to substitute for their lack of experience and be successful in self defense.
As for the issue of lasers, whether or not they are a good or useful combat tool according to the experts is going to be determined by what experts you solicit for opinions. There are experts that say lasers are a useful tool. I would be willing to bet that at some point in the distant past, some "expert" probably voiced his opinion that putting sights on a firearm wasn't a good idea either.
