"meeting these fundamental social responsibilities"
The fundamental social responsibility of government is protecting its citizens, not snooping on them.
Keeping the peace means feet on the ground, visible police presence by affable and polite constables always ready to help while keeping an eye out for shady behavior.
It is costly, doesn't catch everything, but it is civilized and respects the privacy of the innocent.
It was once said : "I prefer to let a hundred criminals free rather than jail a single innocent".
My, has time flown by . . .
