Which sentence among the following the correct:
There was always a guard at the door. It had been that way ever since the labratory was established.
My issue with this sentence is that a guard can't possibly have been posted at the door of the labratory prior to its establishment. The labratory was established first; then the guard was posted. Therefore, is it wrong to say it 'had been that way'?
Which is why my second suggestion is:
There was always a guard at the door. It was that way ever since the labratory had been established.
