It seems that many UN member countries would benefit from a increased police support force. For example, Honduras is notorious for its high crime rates.
This is ostensibly the role that UNPOL is supposed to fill. However, as of this post, UNPOL only has about 12k officers, spread across a dozen countries on various peacekeeping missions. For perspective, the USA has nearly 1M police officers.
Since it seems that there exists a need for such a service, but that service is not being filled to the extent that would arguably be warranted, I presume that there exist political barriers to a much larger UNPOL force.
So my questions are:
What political barriers exist in countries like Honduras that might stand to benefit from UNPOL support stemming from, e.g., a disconnect between country policies and UNPOL policies?
What political barriers exist in wealthier member countries and the UN as a whole to provide funding and/or support for a larger UNPOL?
