Excellent article. I have actually conducted extensive research on this subject for my master's thesis and potentially a book down the road. Consider this...since the year 2000, there have been 3,181 deaths of Americans or foreigners on American soil as a result of terrorism, domestic terrorism, and mass shootings combined. The bulk of that obviously comes from the September 11, 2001 attacks. In realilty, aside from those attacks, there hasn't been any major number of those killed. Wounded is another story. *Note* this number does not include those killed in support of OIF/OEF/OND.
Between 2006 and 2011, there were 87,325 homicides according to the FBI in the U.S (excluding the 9/11 attacks). As pointed out in the article, the NGIC estimates that roughly 48% of all violent crime is a result of gang activity, which using that number would more than 40,000 gang related deaths in America. 10 times the number of those killed in terrorist attacks in half the time. More than twice the number of those killed as a result of terrorist attacks AND soldiers killed in OIF/OEF/OND over the last 13 years in half the time.
Sadly, most mayors and law enforcement leaders are in complete denial. These studies often actually underscore the gang problem as many government and LE leaders are either in complete denial or don't understand what gang activity actually consists of. Even giving a ridiculously low percentage of 10% would still give us more than twice the number of terror related deaths in half the time.
Working gangs for the past 7 years, I have yet to come across a gangster in possession of a legally possessed firearm. Most of these guys are prohibited from purchasing a firearm before they are old enough to legally buy one as they generally enter the criminal system as young as 10 or 11 years old. They are violent felons long before they are adults. The closest they come to legit sales is through their girlfriends who, in today's gang world, are often sought out without a criminal record to help purchase firearms or stash illegal items. Still, they end up in illegal possession of the firearm as soon as they come in the vicinity of it. This was an excellent article, but sadly, politicians don't care about facts or protecting the people or government. They care about furthering their own agendas. Such is the fall of the Republic, as it did 1600 years ago. Just my $.02.
