What a good idea for these knob-heads of young criminals, who delight in robberies of shops, petrol stations, elderly persons et al. Smash & grabs, road rage, & car-jacking.
The sometimes physical injuries' they impart are disgusting, let alone the psychological ones' that the victim has to live with forever.
The reason I say this is: have you noticed how they AWAYS hang or cover their heads, when arrested? They KNOW they've done the wrong thing, so public humiliation would be an idea for them.
Let the rotten fruit fly!
