Why the " shock " ?
Perhaps the G&M could actually visit and investigate a remote reserve and report directly on its findings - instead of merely changing the dates of this standard but stale article ?
( Apologies )
 The investigation might reveal a severe and fundamental cultural dysfunction - a dead end future for the children and youth, dependency on "government", recycling and rationalizing of old events ( residential schools ), lack of initiative, no incentive for betterment, tribal politics .......
ALL of it very controversial and subject the usual politically correct censorship - but until the true root causes are aired, accepted and eliminated this type of sad news will merely continue to provide cheap head line fodder.
