How does the movie Harry Potter and The Prisoner of Azkaban relate to the real world today?

There is an atmosphere of fear in the movie Harry Potter and the Prisoner of Azkaban because a prisoner escapes from a supposedly inescapable prison. At the beginning of the movie, we see how the media covers the events in the wizard newspapers and that there are wanted posters everywhere. The posters are a little scary, with the prisoner Sirius Black jumping out at you with a crazed look.
In our world, unfortunately, a state of fear is very common. We see media coverage not of prison escapes, but of terrorist attacks. This is not to say that we have never had frightening and high-profile prison breaks. Like in the movie, there seems to be a dark, depressing cloud of dread upon us at times when we hear about mass shootings and other tragedies. Dementors may not be real, but these incidents frighten us and soak the life and happiness out of us just the same. We cannot seem to escape the media coverage of tragic events.
With our 24-hour media, there is also a lot of misinformation. In Harry Potter, Sirius Black turns out to be innocent. When everyone is in a hurry to scoop the story, the headline is remembered, not the retraction. A lot of people have been the victims of unfairly ruined reputations.
