Who says the security light was not triggered?
I have one and it doesn't stay on forever if triggered it goes back off after a short amount of time. It is a motion detector type.
No one noticed the light on. At that time of night it would have taken someone awake and looking in that direction to notice it. So saying it was not triggered is a false claim.
It wasn't on when the police arrived is all that can be proven. It triggered when they searched the area.
My neighbor has one in their backyard and the feral cats in our neighborhood trigger it all the time. When they first installed the light, it used to wake me as it shines right into my bedroom. I'm used to it and now I don't wake up anymore when it goes on or off. If I'm awake watching TV or reading I'll see it but I barely pay attention to it anymore. My neighbors had a party last night and I didn't even notice the light on at first but I heard the laughter and talking and then saw the light was on.
There is not a recording device on the light that shows when it was triggered, how many times it has been triggered, what time it was triggered, so the claims that the light never went on or off is not an indisputable fact.
No one can say they they saw it is all.
No one noticed the light being on or off.
A neighbor used to the light would not notice it just like I don't notice it anymore. It is familiar to me and my brain filters it out as unimportant as all my previous brain training has conditioned me to ignore it.
The point about the motion detector light is that there's stayed on for a good time when it was triggered - I think it was 9 minutes. And it was OFF when Waddell arrived, only 5 minutes or so after Darlie made that call, supposedly seconds after the intruder fled through the back door.
How did the intruder flee through the back yard without setting off the motion detector light when everyone else sets it off?
I don't have time to search out the testimony right now, but it was covered in the trial.
