Voodoo Justice in Michael Dunn Trial Again?

In the Internet age with lots of free cloud storage and dirt cheap web cams why aren't new cars and retrofits given exterior audio-video surveillance normally that record the area around an automobile for potential use in court trials? The Michael Dunn case seems like voodoo justice with a prosecutor making inferences and guesses about what might have been heard, what emotions may or may not have been stimulated and what evidence such as a shotgun may or may not have existed. That seems a kind of shoddy cargo-cult approach to legal justice especially regarding the important issue of the freedom of a potentially innocent citizen.

It would be easy for new car manufacturers to install such surveillance equipment that could be turned on or off with a verbal command from the driver. Information could be automatically uploaded to the cloud for storage-perhaps 24 hours of data recycling as in store surveillance cameras.

There are many gangs in Florida and automobiles are a second home for Americans. Hostile witnesses in numbers can have their way in voodoo court settings-voodoo that is if a reliable technological record of what occurred is available. That is the way to go in order to avoid innumerable legal justice conundrums ahead. One could become a millionaire installing such systems for a few easy payments of $19.95. I wish I had production connections in China sometimes.
