Not at all.
I'm saying they didn't have to wait until BK took the family trash to the neighbor's to obtain the family's trash and test it for DNA.
I'm also saying the odds BK was going to throw anything, evidence-wise, away at that point is stretching it.
Thirdly, due to the layout of the neighborhood--the houses setting so far back from the road--it would be difficult to watch the Kohberger's house without being seen. I could be wrong, but the driveway seems to abut a main branch road, where parking likely isn't allowed (MOO). Being LE, they could still likely park there, but they would be highly noticeable. So, they could have (most likely) parked in one of the driveways on the opposite side of the road.
It's also likely the trash bins were next to the houses in the middle of the night. This is just MOO, but where I live, residents do not pull the bins out to the road until morning, and then they pull them back before dark.
As I said before, I don't disbelieve LE got into the trash, I just question where the bins were in the middle of the night and where LE parked to allow them to see what was happening.
