美国有一个同谋罪，英文叫conspiracy.
Conspiracy is an agreement between two or more people to commit an illegal act, along with an intent to achieve the agreement's goal. ... Thus, where one or more members of the conspiracy committed illegal acts to further the conspiracy's goals, all members of the conspiracy may be held accountable for those acts.
同谋团体成员，即使某个人没有直接做犯罪的事情，比如在银行外面接应抢银行的同伙逃跑，开车本身不是罪，但是这个人也会被判处罪行。
