Search Warrants

Dear Sir or Madam,

I am trying to find information relating to the status of requests
for search warrants and the subsequent issuance or rejection
thereof.

Are the requests and/or the warrants themselves public records? Is
it possible to see individual requests/warrants or lists of
warrants sought, granted and/or rejected?

If these records are open to the public, can you please provide
information how they may be accessed, in particular what
information is required to view details relating to a specific
warrant.

Also, can you tell me what aggregate information is kept or
available: e.g. is information produced/published on the number of
requests made / accepted / rejected per month (or some other
period), and is this, or can this be, broken down by court location
and/or magistrate/judge and/or requesting party? Presumably if all
these records are kept in a computer database it would be possible
to get any such report, but I'm unsure what information is stored
and in what format, and whether any statistics are regularly
published or would need to be requested individually.

Thank you for your assistance,

Richard
