Being a pedophile is not a crime. Abusing children or having child pornography are crimes. That's the distinction.

These appear to be related to warrants. If these are related to the 61k sealed indictiments

They are wire tap results

They are not warrants and they are not wire tap results. Wiretap authorization allows you to listen to phone calls. These are pen register and tap and trace requests. PR/TT applications is what they are called in this document. And they date from 2008 to first nine months of 2017. https://www.dcd.uscourts.gov/sites/dcd/files/2018StandingOrderOct2017thruMarch2018.pdf

A pen register allows you to see the list of phone calls made, but you don't know the content of the phone calls. Ever see the TV show The Wire? They would put a Pen Register on the pay phones the drug dealers used. It's less invasive than a wiretap and requires a lower standard of evidence. AND you don't need a search warrant to get one of these approved. Essentially when you use a phone, you leave public records with Verizon or ATT or whomever operates the phone. The government asks the business for these records which the business owns. A pen register captures numbers called from that phone number. A tap and trace captures incoming numbers.

“Basically, a pen register is a device or process which records the telephone numbers of outgoing calls; the trap and trace device captures the telephone numbers of incoming calls.”

Federal authority to conduct the pen/trap form of electronic surveillance is codified at 18 U.S.C. §§ 3121–3127.

Pen/trap orders allow the government to obtain communications metadata–like the phone numbers of incoming and outgoing calls, or email addresses of senders and recipients. Pen/trap orders do not allow the government to listen in on the actual contents of a call or read the actual contents of an email or text.

Again, this list is not sealed indictments. There are many types of court proceedings that cause a case to be sealed.

This is list is in response to FOIA request by a national security reporter, Jason Leopold and the case has been going on for several years. He used to work for Vice News and a ton of other places and now works for Buzzfeed. He wanted to find out how often the government was using pen registers and tap and traces. However, since requests for pen registers are sealed there was no way to count how many cases were sealed because of PR/TT applications (just like there is no way to count how many Sealed Indictments there are. Hint, it's not 61K.) So he filed a request saying presumably sealed case files have an expiration date and he would like this information when the seal was lifted. This is a document he filed in 2013.

He asks the court to unseal these cases when they are done. So there will be no active cases in the list released. He also asks for the government for other information that does involve getting warrant, but that is not released here. According the Court's ruling from feb 2018. It appears that might be released in the future https://www.courthousenews.com/wp-content/uploads/2018/02/leopold-buzz.pdf
