Something about this just doesn't seem very plausible, especially if this kind of thing is happening more than once in a blue moon. Either the video evidence is not as convincing as we're being led to assume (thus leaving more doubt in the judge's mind than ours, even if the person is innocent), or there should be some other explanation.
Lawyers began telling their clients to film themselves in their homes at all times so that they could prove to judges that they were in their homes when the devices went off. That's advice they give because the risks of not doing that are going back into jail. And to prove all that, you still have to go through all that process, filming yourself, etc. It's truly bad.
What’s funny here is that you are displaying misplaced trust in the justice system that exactly parallels my hypothetical judge’s misplaced trust in technology.
Everyone also knows GPS can be spoofed.
Your point?
LOL!
Everybody who has played Pokemon Go knows it can be spoofed!
Because judges are nearly always the kind of people who instinctively trust authority. They wouldn't be judges otherwise.
Hope that helps.
