First off, the only reason why former officer Slager has been charged, is the existence of a video.
Yeah, it's weird! The only reason Slager was charged was because of
evidence. This country is weird that way. And it gets worse! In this country the prosecution has to prove its case. The defendant and his/her lawyer don't have to say a word more during a trial than, "The defense rests," if the prosecution doesn't prove its case.
Now if nads really wants to do away with police, she should notify her local PD and/or SD that she doesn't want them to come to her home in the event of a burglary or kidnapping (in the cases of murder or vandalism there are sanitation and/or public nuisance considerations). And she should post notice on her property to the effect that she will not call the police for assistance in any circumstance.
IOW, she should walk her talk, publicly.
