Detaining does not happen in US but they just get shot by LEO.
A lot of black community will tell you they are improperly taken/shot in for trivial infractions.
Tell me one instance in RU whereLEO just shoot unarmed civilian for minor road traffic stop.
David Miranda was detained at Heathrow:

While I understand US is better than RU,CN they are not that far ahead.
Nit pick is OK but defending CIA is hopeless. Ask amnesty they will tell you more cases.
