This demonstrates the issue of Syntactic Ambiguity. Syntactic ambiguity occurs when there are two possible meanings for a given phrase. The statement "The authorities have denied authorization to the demonstrators because they feared violence." is an example of this because it could have one of the following two meanings:

1) The authorities are denying authorization to the demonstrators because the authorities fear violence from the demonstrators
2) The authorities are denying authorization to the demonstrators because the demonstrators fear violence

While it is rather simple to determine the intended meaning for this sentence, other cases may be less clear. In those cases, Syntactic Ambiguity can lead to an issue where the recipient of the message is missing the necessary external context to determine the original intent, which can lead to miscommunication.
