I'll put it another way. I know that if I snitch on the Mafia I'm likely to be a target, if I do not take steps to anonymize myself and avoid them finding out it was me (like if I do it on video and put it on youtube for instance, telling everyone who I am and where I was doing this) then that danger I put myself in is on me. I put myself in danger with full knowledge of the danger I was putting myself in.
If they do actually kill me, it is still murder and it is their fault. I, however, would fully understand the danger I put myself in.
