If a military base was established along the entire Southern Border, one-quarter mile wide, 2000 miles long, that would be 400 square miles, which is 256,000 acres. Joint Base Lewis-McChord in WA is 414,000 acres and Fort Hood in Texas is 214,000 acres.
As a military base, it would have a guarded perimeter and any unauthorized persons breaching the perimeter could be arrested and kept in military jails pending Adjudication. Enemy combatants could be sent to Gitmo. Asylum seekers could be processed in Immigration Courts, established as large tents every 5 miles along the entire length of the Base, a total of 400 Courts until the backlog is stabilized. Genuine Claimants would be processed into The States, others deported.
The Base might be called Joint Base Alamo.
Now that is some original thinking, I’m impressed.
Not to mention, drug possession on a federal installation is a federal offense. Throw the book at traffickers.
