Yes, the surveillance state is now mainstream, according to a US professor of law, whom no-one could call a conspiracy theorist:

“Harvard law professor Alan Dershowitz stated that President Donald Trump’s longtime personal lawyer Michael Cohen being wiretapped by federal investigators meant America was “moving closer and closer to the surveillance state.” Dershowitz said, “I think we are moving closer and closer to the surveillance state where phone calls are tapped, where emails are secured without a real basis. I think prosecutors should not be seeking wiretaps on lawyers’ offices and search warrants and subpoenas for lawyers’ email files unless they have very substantial evidence of very serious crimes—campaign contributions don’t qualify for the kind of crime that should justify the wiretapping of a lawyer. Remember that when you wiretap a lawyer, you are wiretapping his clients and you wiretapping conversations between a lawyer and the client and you are searching for emails. Where is the American Civil Liberties Union on this? Where are civil libertarians? We live in such a partisan atmosphere, get Trump at any cost that we are prepared to give up our basic civil liberties in exchange for getting Trump.”
