I have personally been on hundreds of jobsites in my life and there are two things I've never seen, 1) strangers walking around the project for curiosity's sake, 2) security cameras on the inside of a building that is under construction.
It's almost as if the homeowner installed security cameras because someone had previously trespassed and stole his belongings.
Something I have seen quite regularly in rural parts of the country is people setting up game cams outside of their project that is under construction, and it's not to capture images of wild game on their property. It was to try to catch the people who were trespassing and stealing their stuff.
Kinda strange how the curious jogger showed up on those security cameras, at night, previously. And came back later to mill around the jobsite again. Just how curious was this not-a-jogger?
In fact, I'm getting ready to head to a job site now that is in a similar state of completion as the one Ahmuad not-a-jogger Arbery was trespassing in the day he was killed. I'll check and see if they have any security cameras set up to catch joggers.
