Which big guy murderers are you referring to?

There are many. Ethan Couch if you want a direct example, but that is one of thousands. A poor African American will get 20 years in jail for possession, but a rich white kid will get a year or two for killing someone in a DUI. That doesn't even take into account the corporations that have made decisions that resulted in many people dying but that never faced jail time.

Will be interesting to see what happens with Elizabeth Holmes.

Even assuming that was the case, the solution wouldn't be vigilantism.

I'm not advocating for murder, but rich people need to be scared of consequences too.

I think this is a very important point. When the rule of law continuously fails there needs to be a measure that strikes fear into those that disregard it.

I personally call this the French/Guillotine Deterrent.
