If you want a simple solution, don't run guns.
I've been doing mining runs with the HEMMTBOX for awhile now, and out of the 20 runs I've done I've been killed and robbed once. I can just buy the guns with the easy money I make mining. I tried running guns recently and there has always been someone trying to rob me, and I've lost more than I made.
Now if you want to keep trying, I suggest putting a tracking device on your HEMMTBOX first. If someone suspicious approaches get on your HEMMTBOX and face it the opposite direction ready to floor it to the nearest HQ, if they catch and kill you just call the cops and tell them the coordinates of the HEMMTBOX, I did this once and they got it back for me.
If you don't want to run just initiate first, take away their gun and tell them to fuck off, if they are wearing rebel gear just engage and kill them after initiating, they aren't worth the risk, you can turn yourself in for a 1K ticket later.
