Conducting a defensive battles is a sure loser and trying to combat drug use by searching vehicles at the border is a last ditch defense effort. It produces some notable wins while being over run by the enemy.
And chasing down some drug thugs and grabbing their cash, even if it's millions of dollars, isn't going to make much of a dent in a multi-billion dollar industry.
“Or are you under the impression that the WOsD is actually working despite all evidence to the contrary.”
What War? 9-11 happens and the U.S. commits its self to spending hundreds of billions of dollars every year into an unknown future to prevent a recurrence and punish the groups responsible no matter where they reside.
The damage to lives and the monetary costs of the country having a drugged and stupid subset of the populace is far, far greater than 9-11.
Yet the lowest and simplest level of the so called War on Drugs, searching vehicles at the southern border is conducted in a hit and miss fashion. Admittedly the vast majority of drugs do get through because the vast majority of vehicles are not searched and unless there has been a change, trains are never searched.
Some war! “B-B” guns against tanks.
At the moment there simply isn't the national will to do what must be done.
Every single Mexican railcar entering the USA is now x-rayed. Train Companies now pay fines of $500 per ounce of drugs found in their cars. One train company (UP, I think) currently owes the feds $400 million in fines for contraband found in their traincars.
