what i mean is: if a law just says 'people can't say mean words', is every private company expected to thereafter analyze all words that exist on it's platform (be it twitter, or sms text, or gmail, etc) make a determination as to whether those words violate the law, and are then expected to take some action, based on it's assessment that a crime or civil offense has been committed? that's what i mean by deputized. if the law doesn't say the company is required to take an action, the company should be mostly indifferent to the law's interaction with third parties. further, it's a bit silly for a law to say that a company should make assessments of criminality or civil offenses, especially if they aren't provided the same legal privileges that police receive for doing the same thing.
