Street Justice as some have said.
What happens when the “system” of government, police and courts fail to protect citizens. Should have thrown a few politicians responsible on the fire for good measure.
Or rival gang, possibly in league with police.
So many deserve to have that justice happen to them.
Every cop show villain and especially the Criminal Minds ones should have slow death by torture rather than a stupid prison term (from which they either escape or have a reduced sentence where they watch TV and pump iron in the weight room or are released due to dna chain of evidence problems. Or a quick gunshot death that is no real justice at all.
