▁clear ▁distinction ▁between ▁the ▁common ▁street ▁gang ▁and ▁drug ▁gang s . ▁On ▁one ▁hand , ▁a ▁drug ▁gang ▁produces ▁strict ▁discipline ▁on ▁its ▁members , ▁who ▁are ▁treated ▁as ▁if ▁they ▁were ▁employees ▁of ▁a ▁company . ▁On ▁the ▁other ▁hand , ▁a ▁street ▁gang ▁is ▁struct ured ▁in ▁terms ▁of ▁" loy alty " ▁and ▁" similar ▁rival ries ," ▁thus ▁producing ▁a ▁less ▁strict ▁discipline ▁on ▁its ▁members . ▁Furthermore , ▁Klein ▁includes ▁a ▁variety ▁of ▁statistics , ▁an ec d otes , ▁and ▁personal ▁experience ▁to ▁demonstrate ▁that ▁gang ▁activity ▁across ▁America ▁is ▁on ▁the ▁rise , ▁especially ▁with ▁gang ▁hom ic ides ▁and ▁the ▁general ▁spread ▁of ▁the ▁gang s ▁themselves . ▁Another ▁point ▁that ▁Klein ▁explains ▁is ▁that ▁the ▁liberal ▁method ▁towards ▁the ▁solution ▁of ▁gang ▁activity ▁is ▁not ▁working ▁and ▁instead , ▁is ▁increasing ▁" group ▁coh es ion ." ▁He ▁bel ieves ▁that ▁the ▁more ▁attention ▁that ▁society ▁gives ▁to ▁gang s , ▁the ▁closer ▁the ▁gang ▁will ▁be , ▁and ▁the ▁greater ▁gang ▁activity ▁will ▁become . ▁From ▁his ▁own ▁personal ▁experience , ▁he ▁tells ▁readers ▁that ▁the ▁programs ▁that ▁will ▁gradually ▁break ▁down ▁the ▁" group ▁coh es ion " ▁will ▁take ▁lots ▁of ▁effort ▁to ▁do ▁so . ▁ ▁Res pond ing ▁to ▁Tr ouble d ▁Youth ▁( 1 9 9 7 ) ▁ ▁Klein ▁and ▁Ch ery l ▁Max son ▁provides ▁their ▁ins ights ▁( in ▁a ▁more ▁philosoph ical ▁approach ) ▁towards ▁the ▁" tr ouble d " ▁youth ▁population
