1. the 'no/fewer guns = no/fewer shooting' fallacy - already defeated by facts in new york, chicago, washington DC, Australia.... google data before/after tight gun control
2. the 'china has go guns' fallacy - irrelevent. different culture... valid data should be from the same demographics before/after gun control... see google above.
3. the 'single data points' fallacy - I heard this, I think that.... while ignoring hard facts.. see point 1. above.
