You can describe what happened - you just have to leave out the names if you're doing it here on Frontier's forum

.
As for your hypothetical scenario - happened often enough. Which is one reason why we got three game modes: Open, Private Group and Solo - with the only difference being exactly that: who you can meet inside the game. And the blocking feature, in case you want to make reasonably sure that you won't encounter the perps again.
For the explorers who want to play in Open, there was/is/are groups who would run escort duty once they got into populated areas. And the (often repeated) suggestion to stop and drop their data before entering known hotspots or more densly populated space. Which all has declined somewhat in the last years, possibly due to the advent of Fleet Carriers, as you now can drop your data at any equipped FC, even out at Beagle Point.
But face it - you were in Colonia (which some people - see DD - want to be a hive of villains and scum), on your way to Jaques (the highest traffic system there), in an Anaconda, in Open. You definitely were not a newbie any more. Anyone could reasonably assume that you were aware of what you were doing. Of course, if it happens, it's pretty much rage inducing. When it happened to me, I lost a (engineered) Beluga full of passengers on the return to Jaques. I also had a (what I thought) capable combat ship stored nearby, so I grabbed that and went back. To get my backside kicked a second time (but was able to get away).
