You’ve joined the detective bureau and are wondering what gear you’ll need to be successful. If you haven’t realized it yet, real detective work lacks the excitement typically portrayed in movies and television. As such, nothing on this list is particularly sexy but they can help you get the job done.
1. Extra notepads and pens
It seems like you never stop taking notes as a detective, so you can never have too much paper with you. Keep extra pads in your car, your desk and your go-bag.
I always use a separate notepad for each case — otherwise, you’re constantly thumbing through looking for that number you know you wrote down but can’t seem to find.
- 6 packs of 3 x 5 inches weatherproof notepad in black
- Notebook is made of 120 gsm rainproof paper
- 100 pages/ 50 sheets per pocket notepad
- Smooth writing liquid ink
- Made with a durable tungsten carbide extra fine tip
- Soft rubber grip
2. Training
Criminal investigation techniques are constantly changing as society and criminals evolve. Ongoing training is the only way to keep up. Check your local training centers or policetraining.net for the latest offerings.
Cell phone technology and genealogy DNA tracing are just a couple of things that have changed criminal investigations dramatically in recent years. The only way to stay current is to be constantly learning.
3. Handheld recording devices
Interviewing witnesses and potential suspects is the lifeblood of investigations. As a detective, you will spend a good chunk of your time talking to people trying to learn what it is they know or don’t know about your case. Having a recording device available is a must for a couple of reasons.
First, it allows you to focus on the person you’re interviewing instead of your notepad. If you’re constantly writing down what you are hearing, you’ll miss out on what the person’s body language is telling you about their statements. For example, the suspect who can’t make eye contact when asked a direct question about their guilt or the trauma victim who starts to shake as they recount their experience.
The second reason is that you need to be recording your suspect interviews. Nothing beats playing a suspect’s own words for a jury. It also prevents the defense attorney from alleging that you twisted a client’s words to make your case.
You could always use an app on your phone but make sure it’s a work-only phone to avoid any personal data being handed over to the defense.
- Power-on password protection
- High-quality recording
- Simple to use with lifetime software upgrade service
- Variable play speed
4. 10-21 Police Phone app
The 10-21 Police Phone app is geared toward law enforcement with a variety of features; one of the most useful is that it allows you to spoof your phone number. You can set it to identify you as law enforcement, but I’ve found it most useful in concealing my identity from suspects. One way it does that is to generate a local number for whatever number you dial.
So, if you’re calling someone out of state or even just another nearby area code, the caller will see a local number that will hopefully increase the chances of them answering. Cell phones play such an important role in investigations nowadays that simply confirming who uses a particular phone is enough to make some cases.
5. Books
You can never have too much knowledge and books are an effective way of gaining that knowledge at a reasonable price on your own schedule.
Here are a few I would suggest to a new detective looking to learn:
6. Investigation software (an agency investment)
Some criminals just don’t want to be caught. Investigation software can help you with that problem by helping you to efficiently search thousands of public databases with a few keystrokes. A suspect’s parent’s address, a phone number they only gave the cable company and out-of-state arrests are just a few things you can turn up.
There are several companies out there with a variety of price points depending on your needs, but if you’re going to do a deep dive into someone’s background looking for that missing link, your agency is going to want you to have this tool.
7. An on/off switch for yourself
The final suggestion I would make is learning to hit the “off” switch when you leave the office. Many of your cases will take weeks, months and sometimes years to conclude, especially when you factor in the court process. One of the things I miss most about patrol was that once the day was over, you were mostly done working until the next shift. Investigations is a different animal, and if you don’t turn it off, the stress will eat you up.
Those are my suggestions to get you started. What would you add to the list? Email editor@police1.com to submit your ideas.
Police1 reader suggestions
- A cellphone with a good, high-resolution camera. Sometimes you have to get your pictures quickly and you might not have a camera available.
- Physical attendance at post-shooting training as much as you can get. Many officers manage to complete their careers without ever having to take a human life in defense. I was involved in a fatal shooting as a patrol officer and later as a detective. The post-shooting classes that my department sent me to paid off in spades when as a detective, I investigated self-defense shootings, both officer-involved and private citizens.
- Mindfulness training and DBT-type therapy. This could potentially address any unknown underlying triggers and mental health issues for the investigators (which ALL of us humans have from time to time), as well as giving the investigators an honest edge on how to be effective, dealing with folks who may be afraid, unwilling or even emotionally disconnected, allowing more opportunity to be aware of unneeded damage and facilitate healing when possible. This type of awareness and training is, in my opinion, the most essential set of tools for being effective, inclusive and kind. This type of intentional awareness will allow investigators to be more prepared and connected.
