The Great Trump Wall not only keeps out illegal Mexican aliens, it stops the smuggling of narcotics into the USA, mainly originating from Colombia and Mexico.

The trafficking of drugs into the USA is a multi-Billion $$$ business and supported by the Mexican government. It is also supported by interests, political and criminal, within the USA.... believe it.

Mexican illegals are also infiltrating into the USA to take over the distribution of the drugs because the distribution chain run by Americans is inefficient and sick,  e.g. shootings in Chicago is over drug turf.

Mexico is a narco-state and their President Pena Nieto of the corrupt PRI party are getting drug money from the drug lords, and that is indisputable.

If the Wall starts to go up, the only recourse for the narco-crooks is to "reach" the POTUS and his family...  with extreme prejudice.... in a desperate attempt to stop the Wall.... believe it too !!!

Watch out Donald... trust nobody!!!
