I have studied self defense and Martial Arts. I am also a health care professional and have studied human physiology. Here is another reference for a person with a reputation and has a masters degree. He has participated as an expert witness. His name is Marc MacYoung.
Marc MacYoung - Wikipedia, the free encyclopedia. Here is a biography of the person. Here is a long paper about Self-Defense which I think would be a good read for anyone on here.
No Nonsense Self Defense - Reliable information for dangerous situations. You know I have left references here APS and its just brings on criticisms and I don't know what I am talking about.
Sometimes people trained as police officers forget that not everyone has been trained as they are. What may be instinctive for them may not be that way for less trained individuals.
Instead of knocking everything I say take the time to read what he wrote, which is free online, and just maybe my constant critics will learn something. The main thing about this is having a CCW and a gun leave large gaps in your defense if you don't include avoid and awareness to name a few. Avoiding a confrontation or fight is the best way to avoid liability, arrest, injury, a damage suit, prison, having to have to work with police, and being caught up in a court case either against a criminal and/or being sued for liability because the DA feels you used excessive force. I would encourage people to read what he wrote. Just maybe people might learn something on this forum.
Nobody knows it all. There are always new things to learn. There are always new concepts to learn and the more you know the more you don't know. I expect an answer like I don't know what I am talking about and Mr. MacYoung is full of beans and is no expert. Maybe just one person could read what he wrote on this link completely with an open mind they might learn something. In Conclusion there is a of lot more to self defense than have taking a class to get a CCW, having a CCW, and owning a gun. What happens if you don't have your gun with you then what are we going to do if confronted, attacked, robbed, an upset potential assailant, a crazy person with a knife, etc?
