But what if it was?
As Harvey Silverglate details in his book, "3 Felonies a Day,[1]" it is absurdly easy to accidentally commit a federal crime and serve prison time. The idea behind vindictive punishment is to make it so bad that you won't commit a crime, but if people aren't aware of the liabilities, how can people truly know their risk? Often intent has to be proven, but if it's in the interest of the prosecutor and their career to get a conviction, they'll get a conviction.
I think to reduce the "arrest/convict, ask questions later" approach is to give every officer and prosecutor a publicly available scorecard that shows their record of rightful arrests and convictions versus wrongful ones, as well as excessive punishment sought and applied in wrongful cases.
There is a scene at the end of the hilarious murder trial film, My Cousin Vinny, when the defense's expert witness completely shatters the prosecution's case, and the prosecutor immediately moves to dismiss all charges. I wonder if that would happen today?
