I'd be so pissed if they broke into my house with loaded weapons simply because the electric company gave them a "tip". Those rat bastards got their money for the bill but then ratted him out. It isn't their job to report electricity use to the police, their not cops, that guy should be suing them and the cops. Cops are to lazy to do any kind of investigation and just kick in doors from miscellaneous tips. What did they find computers and some weed, tax dollars well spent I'd say.
You need to remember the police did not simply break into the person's house. They came with a warrant. There is a huge difference between the two. A search warrant is given by a neutral judge who can see that there is probable cause that a crime has been committed.
