Taylor’s boyfriend fired a single shot and they couldn’t even prove that shot is the one that injured the officer. Charges against him were dropped and the city settled for $2 million when he sued them for misconduct.
They absolutely proved that his shot is the one that injured the officer; he admitted to firing at the police because he didn't know that they were police officers. The city settling has nothing to do with the supposed innocence or guilt of the officers involved. Cities have settled numerous times even when their officers did nothing wrong (see: Mike Brown).
As is stands, the prospect of a life sentence for an alleged crime that didn't even injure a single person is preposterous.
