Another Questionable Conclusion from a Drug Warrior

Yesterday, Mexican soldiers arrested an alleged Zeta outside of Monterrey who, according to authorities, controls 4,000 hit men. Four thousand is a big number, well more than half the total figure of drug murders in 2008. So one guy, whose public profile was nil until his arrest, controlled half the killers in Mexico? Or are most of them inactive (perhaps the Zetas take their managerial cues from the LCF)? The conclusion was based on receipts of payments made to more than 4,000 people in various states around the nation, but why do they assume that all of the recipients of the cash were hit men?
