pawcatch,
Lies, damn lies, and statistics sums it up. One huge problem with using data from foreign sources is the methods used to collate the date. For example: Columbine had, according to US methods, 15 shooting deaths, since 15 kids got shot and died. In other countries (Until recently, 1999 I believe)England would have listed only 2 gun related homocides, since there were only 2 shooters. I tried to compare the stats from foreign countries, that had strong gun control laws, to the US a year ago with little success. The discliamers you have to add to your argument as to how the data is collected, and exacty what constitutes it eg: is suicide included?, makes it hard to use in a verbal agrument, and too wordy for a side by side compare. What I found to be more effective is the use of State Dept travel advisories. The SD usulayy lists any and all advisories, and give reasons, for any area they suspect to be trouble.

Good solid arguments can be formed with the conficting data found here. If strong gun control works, why is travel in Mexico so dangerous and armed crime so prevalent?
