Pixxed off somebody, How else would anyone know? Man, that's a lot of crank, I wonder why they took such a chance shipping that much, I mean, that represents a lot of work and Sudafed, going for the "Big One", nice work, , makes you wonder how much of that crap there really is? Still, I bet made a considerable dent in the drug trade.,,
Just remimber for every single truck like this that gets caught. There are a hundred that arent. Also keep in mind around 15 to 25% of americans are drug addicts depending on the study you quote. You can likely do the math on just how much is being consumed and brought in daily.
As for catching him? Good chance they tipped the whoever was tipped off themselves to distract law enforcement so they could smuggle way more in elsewhere. Pretty standard tactic especially in the age of police hate, underfunding, under paying and under training.
