Moroccans do have a form of OC.
While a lot of Moroccans ( especially in the larger Belgian and Dutch cities) still behave like disorganized street-level robbers, a minority has -especially in Amsterdam- exploited their links with hashish barons based in the Rifian areas ( since almost all Moroccans in Belgium and the Netherlands are of Rifian origin). While bringing in hashish was previously something Dutch criminals did, some Moroccans in the diaspora have also began to organize themselves and start bringing in hash, as well as cocaine.
But yes, most are still disorganized, but an increasing lot is beginning to organize themselves, just like an increasing number of Algerians are beginning to do in France.
