I’ve thought from the very beginning that this thing was simply too sloppy for the Mossad. I believe that the Dubai cops are generating lots and lots of noise to convince their fellow Arabs that Dubai is actually very safe for any sort of business. (For example: Dubai had no problem in hosting a known terrorist. They only had issues when the guy was assassinated.)
I am still convinced that some Palestinian — from either Fatah or Hamas — is rolling on the floor with laughter because Dubai is so effectively covering his ass.
