I understand that no search tool is entirely accurate, but I'm seriously beginning to doubt the accuracy of the Moz keyword tool search volumes for keywords.
For example: I entered "largest police departments" and it says 0-10 per month in the US, despite the fact that that term is directly responsible for 200 hits per day. Many alterations of that keyword come up with 0-10 or not determined.
This is not a small error -- and it repeats over and over for other search terms that I have already ranked for in the US. It's gigantically inaccurate in a massive scale.
