Campus Concealed Carry

I have been thinking about this one for a while. 
There are so many people that are against the campus concealed carry (CCC), but why?  The arguments against CCC are the same ones used by anti-gun people for all laws.  They say that more guns = more crime, erroneous!  More guns = less crime (people are able to defend themselves). 

Please bear with me, this is going to morph into a concealed carry / pro gun tirade.

People who choose to carry concealed are usually law abiding citizens.  Enacting a law against carrying a firearm only disarms the people who follow the law. Preventing a lawfully concealed carry in your store, campus, restaurant, etc. does not prevent a criminal from entering your store with a gun.  They are called criminals for a reason, they have decided to disregard the law against robbing someone at gunpoint.  They will probably not abide by the law that prevents them from carrying in your store!  
 
This is the same thought process about gun purchases! 

My point is that if someone wants to break the law, they can, a law does not stop the crime from happening.
