I like the phrase "snitches get stitches" because it suggests that, in spite of its incumbent violence, the criminal underworld is proactive about timely affordable healthcare.
Rob@GrimmReality I think if you use the entire saying;
Snitches get stitches and wind up in ditches
the benevolence of the criminal underworld making sure you're all stitched up, is to ensure a good looking corpse!
