>public safety is the number one priority for any government
You blanket-declared that any/all governments have it as their number one priority, with no nuance I might add.
Additionally, are you somehow completely unaware that the American government is sending people to that country's worst prison, and that the current president has said he wishes to send American citizens there? This is why American values are at all being referenced here.
Nobody thus far in this conversation has been defending gitmo, the patriot act, or the illegal and unjust invasion of Iraq -- and personally I'm against all three. Yet you're creating false equivalencies, ascribing strawman views to others, and mostly avoiding any nuance to such matters as if the country's underlying corruption and dysfunction which enabled such lawless conditions is any better (which it might genuinely be, but such points ought be evidenced and argued, not declared).
Instead you've transformed it into something approximating: "now el salvador is safe and everyone is happy, there was no need for liberty or human dignity to be respected then or now."
Therein you make yourself out to argue in poor faith.
