The Congress shall have Power...
Clause 11: To declare War, grant Letters of Marque and Reprisal...
In days of yore, any *zeta* caught on this side of the border would have been fair game. Border area property owners, former US LE & Military, etc. should be granted LOM by Congress to nail these guys. Instead of throwing good money after bad with no results, Congress would only pay out once results have been achieved.
I'm not in favor of (drug) legalization, but I'm also against the WOD in the unconstitutional and ineffective manner it is presently being waged. The current tactics and strategy being employed are not only losing the war, but shredding the constitution. It is way past time to relook how this war is being conducted and make some significant changes.
I don't believe it's possible to have a federal war on drugs that's both effective and respectful of the Constitution.
