“Unless I was to poke through my client’s packaging (which, although tempting, I never did), there was no way to verify I was not inadvertently carrying a brick of weed or a firearm in my bag.”

That. Pretty much the first thing that came to my mind, when I first heard about Uber/Postmates etc doing delivery jobs on demand. What is stopping organised crime from getting bunch of “burner” phones to organise a distribution of drugs across the city?

And if you get stopped by police, how do you explain that you are delivering a brick of cocaine?
