Those numbers don't mean much without the ability to compare them to the acceptance rate of warrants in other criminal courts.

I haven't found a single statistic on that seems that no one actually is keeping or publishing it, but every article I've read seems to point that denying warrants is very rare in all jurisdictions.

e.g.: http://tucson.com/news/local/crime/rejection-of-search-warra...

I mean in California police officers can request a warrant and have it signed digitally, and they even got a fucking app for that.

When you automate a system to a point when a police officer can get a warrant on his Ipad i some how don't think that many of them are denied.
