Thanks, though there are Mexican militias in the US. The Brown Berets (Los Boinas Café) were not a gang, they were a militia.

On another note, if anyone could provide any hints as to why my comment made in good faith with an actual link to a reputable site that backs up a well-known phenomenon affecting police nationally was flagged, that'd be great. It's difficult to judge the group-think of ycombinator comment moderators.
