Why throw out illegally gained evidence? Because it&#x27;s pretty much the only censure a judge can do, and it&#x27;s a damn powerful one. Yes, evidence laundering is a problem when it come to warrantless surveillance, but simply throwing up your hands and saying &quot;Well, I guess anything taken from any method and without court approval is okay. I guess judicial oversight is an antiquated 18th century idea,&quot; isn&#x27;t the answer.
