No need to get overexcited about the "right to bear arms." You have to remember that in Western democracies (especially America) the police maintains the public order with an iron hand. Just beacause you have a gun it does not mean that you will use it -- in fact, the majority of people get a gun "for the fun of it," as an insurance that were they attacked they'd be able to get back to the attacker. However, the possibility of being attacked in middle class neighborhoods is minimal and these people almost never put their guns to use. It is not like in some countries where there are virtually no laws and people set the record straight themselves. It is in these countries that the right to bear arms would prove detrimental. For instance, it is well-known that in ex-communist countries journalists are beaten randomly when they publish discrediting articles about a political figure of their country. Not to mention that even politicians themselves have been treated like * & ^ % in these countries (Russia, for instance). Intelligence services' agents have beaten political adversaries of their superiors so bad that they have nearly died; or their houses have come under heavy gun fire. Assassination attempts towards high level government figures are random even after so many years of trying to establish democratic societies.
