As I said, if Motlanthe didn't follow ANC orders and kept Scorpions around, they would've eventually gotten to Zuma.
I remember reading in Gangster State, that if Scorpions wasn't disbanded and Zuma still did all the **** he did, they would've ended him by at least 2011 (would've been only two years into his first term).
And I reiterate, if the Scorpions had weak points and could be simply captured like NPA, SSA, etc by uBaba, why dissolve it and not just capture it later? And the "MBEKI BAD" motive isn't enough.
The Scorpions posed a threat to uBaba and ANC's "time to eat" tendencies... Hence, they opted for the dissolution and of course, selling the Scorpions as being Mbeki's Gestapo (i.e. MBEKI BAD). And what's hilariously ironic is that the SSA became Zuma's secret police/Gestapo during State Capture.
