Very helpful for law enforcement
Got this book recently and I am very impressed and happy I purchased it. I will keep this review short and to the point. This book covers everything with various searches including, cars, homes, etc. Anyone that works in law enforcement should pick this up as it provides what you can and cannot do, along with example cases. Great guide for any rookie and even vets that need a refresher.

A must have for all officers!
This book is a must-have for ALL officers. I use it constantly as my go-to reference for tricky search issues. My sergeant also has a copy and she reads one of the sections (about 1-2 pages) a few times a week during roll call. I hope that the author comes out with another book just with search warrant template language.

Super informative and relieves some stress over questions that I have
Really informative and will help with a lot of questions that I have and questions that others need answered. Have been taking many blue to gold courses and I’m so intrigued to possibly make this a deep learning process for myself.
