No precinct covers the Presidio?
The Presidio is considered federal land. So if I'm not mistaken, the crimes reported there wouldn't go to the city database, but a federal one. This is a guess, but seems likely to me.

#12i would much prefer to see the columns in the initial chart to be horizontal so that the labels were legible. my neck hurts.

#13It would be interesting to compare police data with a sewage study like this:

My guess would be that San Francisco's marijuana and cocaine consumption is at a per capita all-time high, even as police incidents decline.

#14Why are opiates classified as hallucinogenic and not rolled in with heroin?

#15I am impressed by how quickly the notebook goes from raw data to interesting patterns. Nice.
If I wanted to be picky about statistics (I generally do), I'd note:
1. Equating enforcement-related statistics with usage-related statistics is a dangerous thing to do. For example:
a. The rate of non-CRACK incidents in TENDERLOIN is probably low (disproportionate with actual use) due to the focus limited police resources put on crack.
b. I would bet that the high rate of WEED incidents in INGLESIDE / BAYVIEW vs, say, MISSION, is due to police using weed enforcement as a weapon against gangs (and minorities). I mean, people smoke a lot of weed in the Mission.
2. Putting "AMPHETAMINE"-related crimes under "METH" is inaccurate, as is putting "OPIUM"/"OPIATE"-related crimes under "HALLUCINOGENIC".

#16Are there any resources on how to properly format raw data t make it most useful for display on a map? I'm hoping to do a crime map for my city and haven't quite found a good place to start.

Look into d3.js if you want it in a browser, there are a lot of examples. You'll have to re-format the data probably which might be annoying on a large data set, but I think there are tools out there.

#18http://lmart999.github.io/assets/drug_agg.png Looking at this chart and being a bit assumptive, is it safe to say crack use has declined and meth has increased? Maybe meth isn't really a new epidemic with a new user group, crack users just transferred to meth. Basically, those looking for cheap escapist drugs targeted at the very poor have moved onto a new product. I'm curious which one is worse for society and the u…
Crack is a drug popular among blacks. Blacks leave, so does crack.

I've been playing around with cartodb but am more looking for how to first format the datasets to then display them in a meaningful way
