It's naive to pretend the trade-off doesn't exist already or that a decision hasn't been made. The trade-off has always existed- a warrant can be produced to violate your privacy. It's just a question of what the procedure should be, what information can be searched, what situations it can be used in, etc.

I don't think there is much opposition in the general population to searches where probable cause exists. But that is indeed a trade-off between security and privacy.
