> I don't think the DEA is at nearly as much risk of being captured by those they're meant to regulate compared to the SEC. Power and money are extremely concentrated on wall street, and there is a well-documented revolving door between wall street and the SEC that I don't think exists between drug dealers and DEA officials.

The DEA regulates legal distribution of controlled substances (part of which is investigating and enforcing rules about the illegal distribution of those substances.)

Regulatory capture of the DEA wouldn't be capture by "drug dealers" -- at least of the Pablo Escobar, et al., variety -- it would be capture by, e.g., pharmaceutical companies.
