Dr. Reddeck,
You disagree with the outcome. The Court allowed family to have an attorney, but they opted out of that. The Judge made it clear that  complaints were submitted. 
The deceased was being investigated for a crime committed that resulted in his live in girlfriend's death. The search warrant was legal, surprised appearance to serve warrant, this is standard, legal, due diligence process. It was found the officers feared for their life. Obstruction of Justice appears to have come from the deceased. When we look at murder cases, facts matter. It is hard to fathom the fact this woman, girlfriend was murdered. Then appending a subject, who has potential missing peices to a case, then hides that, then places others at risk, what if that woman was your daughter? There were chances to file motions, chances go file orders, chances to seek counsel, be represented. Filing complaints without motions, orders...
Why did he need a warrant? He was not cooperating. Officers did their job.
