Banning guns only affects those who do not want to break the law.  Anyone else will walk right through the ban with a gun and their ill intent intact, making everyone inside a very nice soft target.   Those who carry concealed on a daily basis have to leave their weapons in a car. Much higher likelyhood of theft then.   What do criminals do with stolen guns?  They commit more crimes.  Its said the road to hell is paved with good intentions.  Banning may make some people feel better, but in the end it only compounds the likelyhood of more crime.
