The thing is the process (of being arrested etc) is the punishment. At some point, hopefully, the charges will be dropped. But by then the damage is done, you have lawyers bills, you lost your job etc, etc. So that a$$ gets his pound of flesh. If somehow (though in this day and age you never know) that guy gets convicted, that's just gravy.
Leftists have learned to use the slow moving gears of government to punish.
It works quite well.
