That are a lot of reasons that you might need free stock photos of police. Perhaps you are running a true crime blog. You might manage a local law enforcement agency and need to make flyers to recruit new officers. You might want to sell t-shirts to supporters of law enforcement. Whatever the reason, high-quality stock photos can add a lot of value.
I have put together a collection of wonderful, free images of police. These images have been released into the public domain by the photographers that have taken them. You will still need model releases from the people in the photos if you want to use them for certain commercial works. However, there are at least no copyright restrictions that you have to worry about.
You can also find a number of other stock photos of police on Shutterstock. You will have more license restrictions that you have to be aware of and will need to pay a fee. However, they have an amazing collection of photographs that you won’t find anywhere else.
Here are the photos. I hope they help your project!
