>What is stopping this lowlife
Same as with all other crime, we hope it's the law that stops him. We hope that more policemen want to be good men than bad.
The illusion of safety is based on the honor system. Society doesn't work without that.
That assumes that the people who enforce the law want good people to be police officers, and that has never been the case. It is certainly not the case with our current ICE officers.
Does it actually work like we hope it does?
