This happened locally just a few days ago. Protesters were blocking the street at an intersection where a vehicle came to make a legal right turn. Viral cell phone footage showed protestors surrounding the vehicle before the driver sped through the crowd, running over several (but not killing any) individuals. Everyone on social media condemned the driver, a gentleman in his 60's who was just going home after running errands, for plowing through protesters (ironically in a "white Excursion").

Turns out the driver was shot at the intersection -- twice -- and was injured and was trying to escape with his life.

When the police released the factual statement, it received almost no social media attention compared to the original (and false) accusations.
