Wording an appeal to emotion fallacy slightly differently and combining it with a spotlight fallacy doesn't make the poor, non-evidence based argument any better.
Dunblane and hungerford were statistical anomalies, tragic ones, but anomalies never the less. Basing your arguments around anomalies is never a good practice.
Should we ban peanuts because a small number of children have a tragic allergic reaction to them? How many children is the ability to eat peanuts worth?
I'll repeat the simple question, as you refused to answer it , instead deciding to talk about peanuts (makes a nice change to shoelaces I guess)

If we spotlight Hungerford and Dunblane, had gun laws (such as todays) prevented Hamilton from owning his four (all legal) hand guns, is it possible that either the disaster wouldn't have happened at all, or at least may not have involved so many?
I'd suggest the answer to any rational person is of course yes... But let's see how irrational you can get...
