What does it mean to testify?
To testify means that you tell what you have seen or heard in connection with a crime. As a witness, you play an important role, since what you say can help ensure that a person who has committed a crime can be convicted for it.
In Sweden, there is a general obligation to testify, which means that if you are summoned, you must testify.
It is possible to testify anonymously, but only in exceptional cases. If you feel uneasy about testifying, there are various government agencies and organisations that can provide you with support.
