"Law abiding gun owners aren't the problem, the follow laws... They are the ones who sometimes stop crimes before the police arrive. They are the ones who have CCW permits and stop deranged sociopaths who are going on public murder sprees before they can kill or before they can kill as many people as they'd like to."
Do you have an example of this? I haven't done a lot of research, but it seems that when "deranged sociopaths" do go on "public murder sprees," they tend to have specific targets in mind, say Columbine high school or the Holocaust museum, rather than just random murders of people. And in most of these exceedingly rare cases of mass murder, it's been trained professionals that put an end to the incident, not some Joe Blow packing heat. Even in situations where citizens did act--the Kip Kinkle school shooting and the September 11th flight over Pennsylvania, for example--they acted, and were effective, unarmed.
I mean, sure, public murder sprees happen movies and NRA wet dreams, but not so much in real life. Hypothetical mass murders being an argument for concealed weapons is weak at best. It's specious reasoning because if someone's nutty enough to want to go shooting, they aren't likely to give a shit whether anyone out there is armed or not. You can't guard against something like that any more than you can prevent earthquakes or lightning strikes.
