Wall won’t stop drug flow into US
If you think that a wall will stop drugs from coming into the USA, think about this:
Prisons have walls all around them. They are made of many materials like concrete, brick, stone, fencing and razor wire.
They have guards at all main doors, and drugs of all kind got into our prisons.
The USA has a strong demand for drugs, and someone will take the chance to get the drugs to them.
The wall will not stop drugs.
