There are two things at play here. I understand the constitionality issues. The other one is this strange idea that parents have about the right to privacy their children have, that they are somehow violating their children's privacy if they go into their bedroom, etc. That's just nuts, IMHO.

this strange idea that parents have about the right to privacy their children have

Not an idea that I have :-)

I can't see any constitutional issue, as long as the owner or tenant of the property freely consents to the search.

And I can see why parents might like police help. The police are experienced at finding things people don't want found, and they (should, if they're the anti-gang unit) recognize gang-affiliation items that a parent might miss. I don't know what local gang clothes and marks look like!
