Are Democrats or Republicans more against crime?

Everybody is against crime. The danger for all politicians is that they try to 'prove up' how much they are against crime by passing harsher and harsher penalties. Not a recent phenomena. England once made picking a pocket a capital offense. The hangings of pick-pockets

drew huge crowds, whose pockets were then picked by local pick-pockets.

The tendency for all elected officials, who know you are against crime too, is to use your fear of crime to enhance their electability. In that environment justice goes out the window.
