Cogent and Fallacious Reasoning in Mediated Communication Assignment #1

As I was looking at my Facebook not too long ago I came across a news report showing a man with the title underneath "Good guy with a gun stops second beheading...". I am waiting to take the concealed weapons permit class to get mine so I clicked on the link interested to see what it had to say. Although a lot of this news article talked about how the Muslim religion is a terrible thing I wanted to focus on the fact that a life was saved by a man carrying a firearm having  his concealed weapons permit.
This news article was all for the right to be able to carry a firearm as am I. A lot of people, on the other hand, say this is a huge reason as to why there is more violence in todays world and why more people die. I am not convinced because there are people out there with firearms having a concealed weapons permit there is more violence and death in today's world. I still believe the people who decide to take other lives will do so with or without a firearm. For example, the man who was shot had decapitated a women and was in the process of doing so to another woman. There was no firearm involved in this incident. The man had a knife and was stabbing his victims and succeeded in decapitating one of them. The man was stopped in his tracks only because another man shot him with the firearm he was legally carrying.
In the post it talks about how many people dial 911 in a crisis like this waiting for the "good guy with a gun" to get there. It also states that "we, as a society, trust a person with a gun as long as they have a badge on".  I believe this to be true. I do not believe one person would have questioned this incident if a police officer had shot and killed the man. Since it was a regular citizen who held a concealed weapons permit it is now questionable to some people. One comment on this news article stated "for every one life that a gun saves, there are 100's that are killed". Again, as I said above, if people want to take another's life they can do so without a firearm and have done so many times in the past.
I believe this reasoning is cogent. People are convinced since firearms are the most used weapon causing death that they all should be banned. This does not mean the people who use them to commit crimes will not get their hands on them if they are banned. It also does not mean that crimes will stop taking place if they are banned. Crimes will always take place whether firearms are allowed to be carried by people who carry permits or not. Lots of crimes, such as this one, have been stopped and lives have been saved because of people who hold a concealed firearms permit and carry a firearm. I believe most people, if the situation was presented, would use a firearm if either they or their family was the victim in a crime such as this one.
