Your typical ad hominem attack Tamura, since you have no legitimate argument. Read my posts about why plea bargains are so often made and charges dropped. It's fact that people are charged and arrested then charges dropped and/or dismissed for lack of evidence.  

To spell it out for you, Tamura, so even you understand, a person should only be arrested if there is sufficient evidence to sustain a charge. The charge & the evidence to support them can then be rebutted by the accused.  But there needs to be evidence first. 

You would understand this if you weren't a CO and therefore disdainful of actual evidence. I realize you're used to the kangaroo disciplinary hearings in prison where due process is a joke & anything a CO says is true is taken as gospel, but that's not how it works in the real world.  In the real world actual evidence is necessary, a CO is just another witness who must tell the truth under oath or commit perjury & the accused has the right to actually defend himself
