Ireland does seem to be a better example. According to your wiki link their gun laws aren't that strict. Most of the guns used in crimes in America would still be legal to own as best I can tell. The US system currently seems differently strict as you just need character references in Ireland where America requires background checks.
Not really. The French revolution was internal. A closer parallel would be the Irish War of Independence (not the North, the Republic)
Given that it was actually much more recent conflict than US Independence, you would imagine that Ireland would be holding tight to the same ideals that the nation was founded by armed uprising. Yet, the gun laws in Ireland are very similar to those in Australia, and no-one complains about it. Even the police aren't armed (except for a few "swat" style units).
edit: wrong words.
double edit: Ireland seems more restrictive toward rifles, but rifles aren't that large a problem in the US to begin with. Their handgun legislation seems to make handguns as available as they would be in the US.
