Your stat shows that (i) Myanmar's citizens were not unarmed and (ii) privately owned firearms were more widespread in 2007 when the country had been under the control of an autocratic military junta for decades than in 2017 when it appeared to be transitioning to semi-democracy. Myanmar is certainly not well functioning, but it is also certainly not an example of effective gun controls, or an example of widespread private firearm ownership preventing autocratic regimes from doing what they like.
All I said was that it is possible to enforce gun laws if the government is well-functioning, which was probably an overstatement.
All I'm trying to say is that if the government is serious about gun control and has control of it's law enforcement (which was a proxy for 'well-functioning', outlaws will not have them)
There are a number of countries that have laws on the books, but does a terrible job of enforcing those rules.
All of this is irrelevant to the discussion of whether the laws should exist or not.
For my needs, Myanmar isn't a country worth discussing in terms of gun control because it's not like the citizenry has a voice in drafting policy and owning small arms has been a way of life there for decades, and does it seem to have resolved their issues with "representation"?
The government there has reduced the civilian owned guns by over half in the preceding decade. [1]
Is Myanmar and example of well functioning?
