Laws
Musica is considered a developed and civilized country with a surprisingly complacent citizen base. There is a high quality of life and an average amount of political and violent crime. As such, the current laws are comparable to any real world developed country with similar quality of life.
Musica would have comparable laws to: The EU, UK, and Canada, and Australia.
Gun legislation is most similar to Canada, while non-lethal weapons (e.g. mace, tazers, etc.) are most similar to the USA (i.e. easily acquired and not heavily restricted in most areas).
The primary divergence are the laws against music, which is most analogous to the US's war on drugs.
The Music Ban
Music is not tolerated in Musica. Offenses against the ban are left to each individual Clef to interpret.
Players may come together to form more specific crime classes if they wish, but generally, the crimes break down to whether or not a Clef believes an offender to be affiliated with a gang. Punishment can vary from friendly warnings, tickets, fines, and arrests.
As an example, if a civilian is wearing a set of headphones that is not connected to anything, they might be let go with a warning. Due to Musician ignorance, it is entirely possible the civilian through the headphones were a fashion accessory.
Humming, singing, or otherwise somehow producing music, is a larger offense dependent on the motive behind it and the motivation of the Clef.
Listening to and enjoying music, intent to sell or deal music, or owning a still functional music-producing instrument (such as a guitar) are the worst music-related offenses.
The Political Climate
Domestically
Musicians generally find the Metallica to be benevolent, and therefore are not politically motivated to overthrow the party or incite unrest. The main detractors are the gangs, which the public looks down upon as miscreants.
Since music brings pain to Musicians, there is no drive to sympathize with gang members or the war on music. The highly policed wall border is not of much public interest, and sympathy against cruel punishment to gang members is uncommon.
Internationally
Musica is surrounded by ocean on it's north, west, and southwest sides. To the east and southeast are three bordering countries: Headphone, Indie, and Emo.
The neighbor countries are adversely affected by the Great Wall. Emo, to the south, also has an ocean border, but refuses to participate in trade with Musica due to the Mute Movement. Indie, a landlocked country, must pay high fees and deal with huge delays to trade through the wall. The costs are so great that it frequently will instead trade through Headphone.
Headphone, the northernmost country, has declared itself politically neutral. It generally does not bother trading through the wall and instead focuses on cargo shipments through it and Musica's northern harbors.
Given Emo's political position and Indie's geographical limitations, Headphone is prospering economically. The dissatisfaction among Indie and Emo is beginning to culminate, however, and there are whispers of war.
