自首！？看过警匪片吗？

You have the right to remain silent when questioned. Anything you say or do may be used against you in a court of law. You have the right to consult an attorney before speaking to the police and to have an attorney present during questioning now or in the future.

切记！切忌！

自首就是认罪，当然要定罪。定了罪就是有犯罪记录，不管你去不去监狱。

量刑时可能会有优惠。但是，一般自首是要先在刑期上讨价还价，知道自己的惩罚后才认罪的。
