We can only assume it was issued on lies... why?
Because Pima County SWAT is now on their 5th version of this story and the warrant you speak of has been sealed at the request of the Sheriff himself...
Infact Pima County Sheriff Clarence Dupnik told Arizona Daily Star columnist Josh Brodesky that he may never release the search warrants and police affidavits. Link: http://azstarnet.com/news/local/article_47d3b9b2-8345-11e0-a48d-001cc4c03286.html
This is where you position begins to fall apart... notwithstanding you must engage in accusations of your own (calling folks drug users) to make your rather feeble point...
But anyway...
The department's excuses for keeping all of this information under wraps make little sense. In his May 18 press release (http://pimasheriff.org/bulletins/officer-involved-shooting-update/), for example, Public Information Officer Jason Ogan wrote, "The investigation that lead to the service of the search warrants on May 5 is a complicated one involving multiple people suspected of very serious crimes.
Sometimes, law enforcement agencies must choose between the desire of the public to quickly know details, and the very real threat to innocent lives if those details are released prematurely." Dupnik used the same line of reasoning. "Those are the real sensitive parts of why we are having difficulty with trying to put information out publicly--because we don't want somebody getting killed," Dupnik said.
The problem with that explanation is that the search warrants and affidavits weren't sealed until four days after the raids were executed, right at about the time the troubling questions about Jose Guerena's death began to make national headlines...
You can assume anything you wish but there are investigations as there should be and when they are complete then there will be the answers for you.
