[quote=Blogstar]Do cops/ DA know how much lying their cases will come up against? Yes. They live with this every day. How many cases are settled with a hand slap because it is too costly to fight against defense lies, I mean alternate versions? Are the cops kind of powerless to do their jobs because of it , some might think so.[/quote]
Police officer duties are completely separate and apart from penalties under the law. The police officer is not the jduge or the jury and has no impact on sentencing. The police are only there to gather facts and arrest suspects. They shoudl not dispense street justice.
