Drug bust

Is it just me, or does drug trafficking seem more brazen when it involves a convoy in Tijuana?  In general, drugs are hidden: in people, in cars, in submarines, in planes, boats, etc.  A heavily armed convoy suggests less concern about hiding and more interest in sheer bulk.  It also suggests a striking lack of concern about being discovered.  That is the bad news, though at least the good news is that the government had gathered intelligence to intercept it.
