There was a follow-up story published yesterday to the events 2 years ago(read about it here.....http://www.cagepotato.com/thwarted-...ain-suspect-maryland-serial-killer-case)where MMA trainer, Lloyd Irvin's home was invaded by two gunmen(Vera was staying with Irvin at the time). Irvin used his grappling and anti-weapon disarm training to strip the magazine of a gunmen and they fled. The follow-up story indicated that one of the gunmen was an alleged serial killer who worked for UPS. This guy had killed 4 women before. http://www.wusa9.com/news/local/story.aspx?storyid=104867&catid=189 Interesting story that really emphasizes the need to take some weapon defence classes at some point. Lloyd had been teaching these techniques to police and military. I know there is a lot of debate on the proper protocol in the case of a home invasion, but really every situation is different, and it can be assumed this wasn't your standard robbery. It's very likely the situation could've become fatal.
