The real idiots you can't stop but their punishment keeps the rest of us plebs in line.
Does it really though?
As I'm sure none of you remember, a few years ago a young fellow received jail time for street racing(in a new factory estate at 3am) in Melbourne. The idea was to make an example of this kid to deter others from doing the same. 5 years on, nothing has changed and nobody even remembers this poor guy even existed let alone his stupid punishment. How can you expect something to act as a deterrent if no one remembers!
Punishment to fit the crime. You cant punish someone for what COULD happen.
It needs to be stopped but you wont stop it with harsher punishment and it's not fair or just.
