You will no doubt have heard that a case of Sudden Jihad Syndrome was stopped by an off-duty police officer yesterday, in St. Cloud MN.
Turns out the "off-duty police officer" is a reserve policeman who owns an indoor range and gun shop, and shoots in USPSA and 3 Gun competitions. (Man Who Shot Crossroads Mall Terrorist Is USPSA Competitor, 3-Gun Shooter – Bearing Arms)
Here's the web site for his busienss: Tactical Advantage, LLC
So, you know, if you're in the Gopher State, look him up.
UPDATE: When Are Liberal Laws Good? When They Relate to Guns | Power Line points out that he is a reserve police officer who is not scheduled to work for at least two months.
