Legal Aspects of Warrant Service with NVG

One of the things I like best about being a travelling instructor is meeting cops from all over the place and talking about the similarities in the job regardless of jurisdiction. Some of the similarities are funny; like nobody has ever owned the pants they were wearing when dope is found in the pockets, “These ain’t my pants Officer”. Some similarities are also command staff personnel who are living in the past and are actually roadblocks to progression. Some of this based on how we did it back in the day, disconnect from the street, and some of it is not embracing technology due to bad information or lack of knowledge. All of those things seem to manifest themselves in regard to NVG use for Warrant Service by SWAT units. “There’s case law that says you can’t use NVG as cops!”, my response has always been “What is the case?”. And then I get the blank….. Here is the reality, there are plenty of cases that talk about NVG and Thermal image intensifying devices in regards to the government using them to obtain information to obtain search warrants. One of the earliest was U.S. V. Lee, a prohibition era case

PSA for Buying Night Vision/Thermal Equipment

When buying 'new' gear, please take the time to find out some pertinent info: 1. Who is selling it and what is their role in the sale? 2. Who is building the equipment and what qualifications do they have? 3. What are the warranty and return terms? I was recently asked to check a pair of goggles over that had been purchased by an individual from a 'dealer'. The individual had some concerns with a few things and shipped them to me. Upon inspecting them I discovered several used parts, pieces missing (o-rings etc) and poor workmanship. The tubes performed terribly on my test set and I opened them up to discover a pair of Russian Gen 2 WP tubes (believed to be Ekran) and not the L3 WP Filmless that they were sold as. If anyone has any concerns regarding an item they have bought I would be happy to help and can walk through what 'red flags' to look for at ryan@nightlongind.com.

Night Vision Quick Focus Caps

Using NVG’s for a multitude of Law Enforcement tasks presents some challenges from typical white light jobs. One of those challenges is that the NVG is focused at a given distance, typically at infinity. The problem with this is when you need to see or examine something at close range. This requires that the NVG be manipulated to change the focus point, which in turn creates a new issue being that you cannot discriminate something at distance because it is blurred. There are a few remedies for this, one of those remedies is to make a tight “OK” hand signal and place that over the objective lens. This blocks the number of photons entering the tube and changes the focus to being much closer. You can adjust the size of the “aperture” by simply making a tighter or looser “OK”. Benefit is it’s free and you always have it, down side is trying to determine the right size and also manipulate other things with the hand that is occupied making the “OK”. Several manufacturers make focus caps, they range in price from over $200 to $9. They all do the same thing, reduce the numbers of Photons entering the tube

LE use of NVG for Warrant Service – One Cop’s opinion.

I have been a SWAT dude for over 20 years, during that time I have seen huge advances in tactics, techniques and procedures as well as gear and supporting equipment. Indeed, I tell new guys that I wish I was starting my SWAT career today versus being at the end of it. We have come a long way since Balaclavas, Command Jac vests with K30 plates and MP5’s. A big reason for this growth and increase in skill is directly related to the GWOT. America’s heroes in foreign lands have discovered that technology, when used correctly, is a force safety multiplier unlike anything else. This is particularly true of night vision capabilities and supporting gear. It is far past the time that domestic LE catch up. As I said earlier, I’ve been kicking in doors since 1995. Since NVG technology was nowhere near where it is today, and the cost was also extremely prohibitive, SWAT teams in America were simply conducting warrant service with flashlights when conditions were such that you had to see in the dark. Many different white light techniques and team tactics with white light have been developed and used over the years. During all that time,
