Has anyone had success getting residential mail theft (or burglaries) prosecuted using video evidence? Around these parts (SFBay California), porch pirates and burglaries seem rampant, yet there's very few perps apprehended. Legislature doesn't help, since it takes more than a $950 theft to be a felony (misdemeanor below that).
You are not alone. Unfortunately, any time the population of a U.S. city grows past a certain point, law enforcement ceases to treat property crime as a crime anymore. The police won't pursue the perpetrator, and the district attorney will refuse to prosecute. Property crime becomes "small fry" to them. If you've been burglarized, that's what your insurance is for. The police spend their time and effort on violent criminals instead.
We've had numerous burglaries and auto break-ins in the twelve years I've lived on my street. With the exception of one neighbor across the street, I have never heard of anyone who had any of their property recovered. And even in that one case, no one was ever arrested; the pawn shop where the perp sold the stolen items was forced to return them, and that was it.
One guy was arrested last year after having broken into literally dozens of cars all over the midtown area (with people posting videos of him on NextDoor nearly every morning). And people on NextDoor already knew the guy's name from previous arrests! The police caught him with a backpack full of stolen items after a neighbor woke up in the middle of the night and watched him breaking into his car. When the neighbor showed up at court to testify, the perp took a plea bargain with a 1-year sentence. He'll be out later this year, and will almost certainly begin breaking into cars again.
A package thief is currently being tracked on NextDoor. There are multiple images of his car. His license plate has been recorded and broadcast to everyone. Yet he has been stealing packages from front porches for weeks, some just last Friday. The police have to know who he is, but nothing is being done.
It is incredibly frustrating, but it hasn't prevented me from installing my cameras, for two reasons: (1) cameras clearly have some deterrent value, and (2) my insurance company is more likely to take action if I give them the license plate and the video, even if the police won't.
