FYI: This is Belize, not Afghanistan. I know to many US-ians with limited world views, they may seem like the same things, but they aren't. Comments like this reflect poorly on you.
In Belize or the US it's the same. Police want to question at their own facility so they can employ unfair methods and detain for trial if they wish. I did put "months" instead of "years" because presumably in Belize it's not as bad as in the US.
