El Salvador, a country with the highest murder rate per capita in the world, passed emergency measures to enact strict antigang policies under the leadership of the young President Bukele (same guy that legalized bitcoin). Bukele was the first 3rd party candidate to win and break the 2-party duopolicy that ruled el salvador since 1970s
The antigang policies included a strict no-phone-calls while in jail policy. Other policies included jamming cell signal in jail, no visitors, and temporary holding period (without charges) was increased from 2-3 to 10-15 days. All this was allowed under emergency measures voted by congress supermajority, which enabled special police powers for 30 days. The emergency measure has been renewed 10+ times already.
Murders have gone down 92% [1]. There are entire neighborhoods that have recently opened small shops for the first time in decades (it was impossible to open any viable business due to crime).
9 out of 10 salvadoreans is happy and plans to vote to reelect Bukele in the upcoming election [2]. el Salvador congress is updating the constitution now since it does not allow re-election.
The approval rating of ~90% is the highest of the entire western hemisphere.
