Re:Rule #1 (Score 1)

In Israel [...] everybody has firearms at home [...]

Actually, Israel regulates firearms very strictly. Most civilians do NOT have firearms and there are stringent requirements for attaining a license, including major bureaucratic hurdles, interviews, training requirements, and age restrictions. For example, people under the age of 27(!) have to get special dispensation to carry a firearm. Also, military training (which is relatively ubiquitous) is not enough to get a license, and even a civilian who actively serves in the military Reserves cannot get a license to carry firearms as a civilian without going through the same process everybody else has to. Here's an article from July 2013 on one of Israel's more popular news sites with numbers. The article is in Hebrew, but Google Translate or the like might be able to help. http://www.ynet.co.il/articles/0,7340,L-4412031,00.html
