Different Notebooks for Law Enforcement

1.  Rite in the Rain Notebook  - This notebook would definitely be my first choice considering that it is weather-proof. This brand "Rite in the Rain" also has notebooks of all sizes. I would pick the 4 5/8" x 7" side- spiral notebook because it is easy enough to carry around and is large enough to write an adequate amount of notes. I prefer the side spiral just because I have always used them. The only downside to this is you must have the proper writing utensil because pen will not work on a rainy day with this notebook. 
2. Minimalist Ideabook, Action Publishing -  This notebook would be my second pick because of the size (5.25 x 8.5),
   minimalist design, and alternating line and graph pages. The alternating pages allow for more drawing and sketching. Unfortunately, this notebook is not weatherproof. 
3. Five Star Notebook -  This last notebook would be my last choice. The size of the notebook is good and it allows for space for field notes. This notebook only has lined pages and is not weatherproof. The cover can be though. I would use the 6" x 9 " size because it is not too big but not too small.
