There are two types of covert entry search warrants. One type authorizes officers to clandestinely enter the subject's home, look around, access e-mail and other computer files, and copy or photograph what is seen. The officers are not permitted to seize anything. That's why this type of warrant is known as a "sneak and peek."
The other type of covert entry search warrant allows officers to seize evidence that's listed in the warrant. If you want authorization to seize evidence, you need to make this request when you apply for the warrant—you need to convince the magistrate that there is a reasonable necessity for the seizure of evidence. The magistrate will decide whether to authorize the seizure.
In our hypothetical case involving Armen, a covert entry search warrant would give officers the legal authority to sneak inside Armen's residence. The clandestine peek at his computer records and other evidence likely would lead to a treasure trove of information. Later, when they need probable cause to apply for arrest warrants or for search warrants that authorize the seizure of evidence, officers could use incriminating information they found during the sneak and peek.
To avoid tipping off the subject, anything moved during a covert entry search (such as a stack of papers), needs to be put back in its original place. And search team members need to be careful to leave no trace of themselves on the premises.
Covert entry search warrants are a valuable tool, particularly in the beginning of complex investigations involving multiple subjects. Use sneak-and-peek warrants to collect information that uncovers hidden assets, identifies criminal associates, and identifies victims.
