Zap... the truth is that all cases CAN be solved. It's true that not all cases ARE solved. And it is also true that in unsolved cases there usually isn't anyone to blame for the fact that they remain unsolved. But there is never a good reason to just accept that unsolved cases will always exist so that's "just the way it is." That's crap. The cases may be unsolved FOR NOW... but they are not "destined" to stay that way and none of those cases should ever be set aside permanently as if the investigators have just given up and written any of them off.<quoted text>
No, not every case is solvable, that's just the way it is sometimes. But when it is, it is still up to the DA to file charges and prosecute.
There is a percentage of homicide cases in this country right now that have gone unsolved... and yes, that's the way real life is. And I guess if there are really adult human beings out there who actually compare real life homicides to television shows like CSI Miami, then they likely are disappointed that these unsolved homicides exist. But it seems to me that disappointment in their community law enforcement might be the least of their worries, since it appears they live in an alternate reality.
And just as a side note... the OSBI are not only called in on "the really hard cases" as if they are Superman being summoned by Lois Lane. They are brought into cases for random reasons, sometimes simply for legal reasons, sometimes simply for added manpower when a local police force is small or inexperienced due to low crime rates in the area. Not all their cases are difficult to solve in the least. There are local police departments and sheriff's departments that handle far more complex crimes every day and do a fine job without the help of the OSBI... and likely prefer it that way.
