I personally do think it's a good thing that in many countries it is illegal for anyone but the police to carry firearms, because it reduces gun accidents and (non-premeditated) murders and makes it more difficult for small criminals to obtain them.
Of course these points are debatable (and how far they apply depends on the nation) and suddenly banning guns in the US would not be a good idea because they are so widespread there; if practically all criminals are armed it does make some sense to also arm civilians for self-defence.
As far as mass shootings go: banning guns would be completely ineffective. Insane people like this will always find ways to obtain them. Just think of the shootings in Norway, Finland and Germany.
There is really nothing you can do about these kinds of shootings; just be glad they are still very rare. The chances of you being killed by a drunk driver are still much, much, much higher than you being shot by a madman.
