It's actually a little easier to notice and cut off power to a large conspicuous party than it is to notice drug deals are going down to do busts. It's not like all the dealers are screaming YEAH WE LIKE METH and dancing under a stream of cocaine with 20 other people clapping their hands while Billy does a kegstand.
And the action taken to shut down someone's power is to call the power company and tell them to do some clicky clacks on a keyboard.
So definitely an apples and oranges comparison. That said, it probably would be a pissing match ultimately as that person said.
