Your "logic" is defective. Clearly the pervasiveness of guns in society now is not stopping these crimes and murders but actually increasing the incidences.  How many mass killings have we had recently? This is worse than it has ever been. The pervasiveness of guns in society did not stop this and rational thought would lead us to the conclusions that more guns, less gun control, more untreated mental illness, more access to weapons designed for assault have led to more mass murders - not less. More guns have not stopped these criminals nor did a conceal carry stop any of these shooters.  Your wild west fantasy is just that. 

NOW is the time to talk about gun control and reducing the number of guns.  Australia did it right.
