SaintSatan,
Some of these people use lies or misdirection as a policy to protect themselves or others. Maybe that's a trait of the irish. Anyway, i don't know if one should condemn those lies.
In the context of the example you were giving, that of people helping other people, there might be a need to lie.
Now, as regards the Society in, say, dealing with the press over molestation issues, such lying has been properly condemned here before.
A long time back, someone pointed out the counsel of Christ at Matt. 10:16 : "Look! I am sending you forth as sheep amidst wolves; therefore prove yourselves cautious as serpents and yet innocent as doves." And examples were cited where Christ appears to okay lies, deception, misdirection, and so on.
This brings up an interesting point: if someone puts you in a position where you feel you have to lie (for your own safety, as in concealing something about you that you reasonably feel they'd react with extreme violence to, as one example), who is at greater fault--the liar or the person who makes you afraid to be truthful?
Granted the obvious answer is "Well, I'll tell the truth and God/Allah/The One/Etc. will protect me for doing right" (for those who believe in a Supreme Deity). For those who feel there are serious reasons not to believe, then hasn't the person forcing you to lie (if pressed) committed the graver offense? OTOH, if you claim belief and yet lie, isn't this lie a loss of faith on your part?
