You do realize you are invited everyone with an opinion to speculate on what they 'think' LE might do yeah? So please take all replies including mine below with a pinch of salt. Controlled delivery attempt's to PO boxes are rare unless you have ordered a large amount of course. I can only comment on what I have heard can happen in my country and that has included LE obtaining CCTV footage of the person collecting the package and using that to build a case with other surveillance intel, basically letting the drugs through and then busting the person later. I have also heard about the 'card in the box' scenario saying please come in and sign for your package which could go either way as sometimes everything is just fine and others not so much. Bottom line there is HUGE amount of uninformed conjecture on here and very little substance of fact. Let the speculation commence!
