There are certainly exceptions to the hearsay rule. By some counts, there are about 30 such exceptions. For example:
- Spontaneous and excited utterances. What this one says is that a person's statement may be used as evidence if they saw something happened and were heard to blurt out a reaction to the event. This is allowed because they did not have time to think about the event and to, perhaps, fabricate a statement about it.
- Declarations against interest. If someone says something that would not be helpful to them, the statement can generally be admitted. The idea is that they would have no incentive to lie and therefore the statement must be truthful.
