I want to know the answer to the following question:
Along with anti-death penalty advocacy, why has there been a shortage in drugs for lethal injections in the United States?
All the background I'm provided with is that "The European Union has outlawed the export of any product that could be used in an execution; this has prevented executioners from using EU-manufactured anesthetics like propofol which are needed for general medical purposes.". Is that enough to answer the question?
Answer: no
