Humans are visual animals. That is why the power of video evidence can be so persuasive in a trial. Combine that with the fact that video and surveillance cameras are seemingly everywhere, and it feels like every crime gets caught on video, and when it does, there is no defense.
In many cases, there are stories behind video. Someone who is supposedly caught on video committing a crime still has every right to his or her constitutional rights, including a trial and a defense.
