Fortunately, this is not up to the prosecutor.
RCW 9.94A.411
Evidentiary sufficiency. (Effective until July 1, 2007.)
(1) Decision not to prosecute.
STANDARD: A prosecuting attorney may decline to prosecute, even though technically sufficient evidence to prosecute exists, in situations where prosecution would serve no public purpose, would defeat the underlying purpose of the law in question or would result in decreased respect for the law.
GUIDELINE/COMMENTARY:
Examples
The following are examples of reasons not to prosecute which could satisfy the standard.
...
...
...
(f) High Disproportionate Cost of Prosecution - It may be proper to decline to charge where the cost of locating or transporting, or the burden on, prosecution witnesses is highly disproportionate to the importance of prosecuting the offense in question. This reason should be limited to minor cases and should not be relied upon in serious cases.
...
...
Crimes against property/other crimes will be filed if the admissible evidence is of such convincing force as to make it probable that a reasonable and objective fact-finder would convict after hearing all the admissible evidence and the most plausible defense that could be raised.
