I gather that the neighboring county department, where the alleged theft allegedly occurred, was going by the "find my iPhone" app, which they said is typically accurate. However, they said that the location had moved and as of 2 hours after my visit, it was now a block to the north from me.
So the thief might have been walking up the sidewalk in front of your residence when they pinged it.
Or ... Even the find-my-phone app relies on GPS. I have my own stories about how accurate GPS isn't. The one most appropriate here is theone where I was in the driveway on a Saturday, working on a Jeep, when a ratty old Ford pickup came roaring down the driveway. A very scruffy looking guy got out, and I was already in Condition Orange because I wasn't expecting anyone, and nobody ever just drops in on me.
But, I tried to be polite, so I asked if I could help him. "I'm here to cut the trees," he said.
"What trees?" (In fact, I had several trees that had suffered serious damage in a recent storm, but I had already hired someone to take them down.)
"You know, the trees you hired me to cut down."
So much for being polite. "I don't have any idea what you're talking about or who you are. I haven't ever seen you or talked to you before and I certainly haven't hired you to cut any trees. So what's the deal?"
At this point he started mumbling about his GPS said this was where he was supposed to be. So I asked what the address was he was looking for. It not only wasn't my house, it wasn't even on my street. The house he was looking for was on the next street over, 3/4 of a mile away. The funny part is that my wife's GPS shows us on that street when we're parked in the driveway.
Don't trust 'em.
