It doesn't matter. As a kid I would bike over to the construction site of what would be my family's new house dozens of times.
IMO, it was the midpoint of a 5 mile run, where he could take a break and check out something cool.
My husband and I bought a new build three years ago. Over the course of several months from the time the foundation was laid we both, at different times, wandered around the worksite after all the workers were gone to check out the progress and get an idea of what the finished product would look like. And we weren't alone. We saw several people who ultimately bought homes too.
I think all kinds of people just have a general interest in construction progress. That's why when you are in huge cities, the hoarding that goes up has viewing windows every 20 feet or so for people to check it out. It seems to be a universal interest.
And while the general population would never think to trespass on an enormous commercial building site with 40 foot long rebar sticking out of the foundation 70 feet below there does seems to be, during early stages of construction of residential homes, an acknowledgement of that curiosity. Once things that are attractive to thieves, like copper, furnaces and HVAC are installed, the worksites are locked.
If English was that concerned with the opportunity for theft he had ample time to ameliorate the situation by posting No Trespassing signs and boarding up the entry to the site.
It's obvious to me that anyone who was aware of the numerous people who entered the site, they were only concerned about one of them. And the thefts that TM mentioned to LE had absolutely nothing to do with English's property, since HE didn't know exactly where the theft of his property occurred.
Only a weapon in an unlocked car was recently stolen in that community. And lo and behold, it was stolen from a self described law and order type who didn't lock his vehicle. Lucky for him it was an unregistered weapon with an unknown serial number. So there was no way to identifying the hapless owner if it had been used criminally or worse killed some local kid who was looking for loose change and ended up hitting the motherlode. IMO, it could be a ghost gun, a phantom created to subliminally suggest AA was responsible.
