This is gonna ruffle some LE feathers on here, but if this can keep at least one person out of jail then I'll consider my job complete.
I have access to a police field manual. Everything is covered here. What they do in high speed chases. How they handle drug intake. When to prosecute. The whole nine. This is everything you want to know about the OTHER side of the playing field.
Couple caveats: Its for USA cops
Its only for a single city. Every city will do things differently. However, what's done in one city is probably not much different from others.
It's long. Probably about 1000 pages. But ctrl+f is your friend. Youd be surprised what youd find in here. I obtained this completely legally, btw. It's public record.
If there's enough interest I'll throw it on a market. Any takers?
Edit: Here it is. Enjoy. Stay out of jail.
EDIT 2: Heres a working link https://infotomb.com/i8ome
Any info on CD's or shipment profiling? How they monitor drug dealers?
