This was not a death by power point class. VERY Informational, that is still relevant today, and actually taught by someone that has real world experience.

This was a very informative class and well presented. Bringing knowledge of this gang to Illinois aids is very appreciated. IDOC has very limited outside training when it comes to non Illinois based gangs. This helps us manage and understand S13 in IDOC settings.
