Redaction Methods

Henry Waldock
Last updated: 2012-10-31

"Redaction" is the removal of information from a document.

When drafting an application for a warrant, production order or similar order, you must give "full and frank disclosure" to the justice or judge who grants the order.

Such applications often include secrets which your sources told, in the confidence that you would not reveal their identities to the suspects. To satisfy your obligation to the court, you must include all detail relevant to the informants' trustworthiness, and the reliability of their information.

To protect the sources, you must ask the court to seal up (hide) some or all of your application.

If your investigation leads to charges, the defendant may challenge the lawfulness of the judge's warrant or authorization. When doing so, the defendant enjoys the right to see all of the application - except those parts which tend to identify the informant.

Prepare your application to redact those parts.

The trial judge will decide, based only on what the defendant sees, whether there were sufficient grounds that the first judge or justice could have lawfully granted the warrant.

Therefore, you want to leave as much information as possible unredacted, without giving the defence information which tends to identify your source.

Black Felt Pen

If you draft your application without considering how it will look after redaction, you will give the trial judge an incomprehensible mess. For example, this looks fine at first. Click the button below to see what material which tends to identify the source, and what happens after you run a black felt pen over that material:

  1. Confidential source A told me that on December 6, 2009, he ate dinner at Henry Waldock's house. While he was there, he saw Mr Waldock receive 20 or 30 packages of cocaine. Mr Waldock told him that this delivery was “the best powder he ever got from the Colombians”.
  2. I have received 24 tips from Confidential Source A in the past 3 years. Of these tips, 7 were proved reliable by subsequent arrests of the suspects involved, and seizure of the contraband identified in those tips. 4 other tips the source gave matched tips from different tipsters and and 4 tips matched information gathered by police officers during their own investigations.  I have no information to confirm or contradict the remaining tips.
  3. Confidential Source A has the following criminal record:
    1. 1999-12-21    Perjury 6 months
    2. 2001-01-13    PPT 12 months
    3. 2005-05-15    Obstruct P.O. Suspended Sentence 1 year

Summarise + Detail

Think in advance what the black felt pen will do. Then write a summary which you can give to defence. Under it, list the dangerous details in a sublist. The black felt pen will leave the summary, and remove the details.

  1. Confidential Source A told me that in early December, Source A attended Henry Waldock's house, where Source A saw a large quantity of cocaine. In particular:
    1. Source A attended on December 6, 2009;
    2. While Source A was there, Source A saw Waldock receive 20 to 30 packages of cocaine;
    3. Waldock said that this delivery was “the best powder he ever got from the Colombians”.
  2. I have received 24 tips from Confidential Source A in the past 3 years. Of these tips, 7 were proved reliable by subsequent arrests of the suspects involved, and seizure of the contraband identified in those tips. 4 other tips the source gave matched tips from different tipsters and and 4 tips matched information gathered by police officers during their own investigations.  I have no information to confirm or contradict the remaining tips.
  3. Confidential Source A has criminal convictions for untruthfulness and drugs, in particular:
    1. 1999-12-21    Perjury 6 months
    2. 2001-01-13    PPT 12 months
    3. 2005-05-15    Obstruct P.O. Suspended Sentence 1 year

Tear-away

This technique sequesters all the dangerous material on a separate page. Instead of running a black felt pen over the dangerous material, you simply "tear away" the appendix, and give defence counsel and the judge what remains.

  1. Confidential Source A told me that in early December Source A attended Henry Waldock's house, where Source A saw a large quantity of cocaine. Further details of this information are attached at Appendix A.
  2. Confidential Source A has criminal convictions for untruthfulness and drugs. Exact details of these convictions may be found in Appendix A.
  3. I have received 24 tips from Confidential Source A in the past 3 years. Of these tips, 7 were proved reliable by subsequent arrests of the suspects involved, and seizure of the contraband identified in those tips. 4 other tips the source gave matched tips from different tipsters and and 4 tips matched information gathered by police officers during their own investigations.  I have no information to confirm or contradict the remaining tips.
