A cheap source of teeth for aquarium gravel
They are either extremely stupid (as it is obvious what has happened here) or they know that this sort of thing can be gotten away with, with very little risk.
If the owners burnt the place down, then knocking the whole thing down rules out finding any proof of arson, replacing a criminal charge with a possible council enforcement issue.
And it would only be some patsy that actually did the burning, just as it seems to be some patsy who owns the company that bought the building.
Police should have had the place cordoned off as a crime scene. But if there are organised crime types involved then they'll have filth on payroll.
It's all so fucking blatant that they must have known they'd get away with it.
