Let us not forget the taking of a Moscow theatre in 2002 where 850 people mostly children were held captive and 129 died as a result.
Hearing about the buses reminded me of Lt. Col. David Grossman's warnings, to us (CPD) officers who attended his in-service training, about inpending terrorist acts against our children. The Lt. Col. made it clear that Islamist have every intention of attacking our schools and killing our children. This piece by SCC caused me to go to Grossman's website for further insight where I discovered a great article called Mass Slaughter In Our Schools: The Terrorists' Chilling Plan?. The piece is a 3 part article that covers subjects in parts 1 & 2 like; why schools, how we know they are coming, terrorist tactical model (Beslan), thwarting the terrorist and Grossman's 4D's
Part three deals with how to prepare yourself. We all have taken our kids to school at one time or another if not every day. And the emphasis is to "always carry off-duty. Always." the article has suggestions for individual officer preparedness and suggestions for depatment training. There may come a time that you may be the only line of defence until the cavalry arrives.
The bottom line is to stay alert and be prepared to protect our children.
