If they had changed a few things it would have been more fair. They should have had the bad guys who walked into the classroom with no prior knowledge that there were armed students in the classroom and maybe even had multiple students in the classroom with guns. It sure seemed like the bad guys not only knew there was an armed student but they probably had prior knowledge of which student was armed.
How about having some of the other students in the hallway outside the classroom so that they could enter the room or wait for the bad guys to come out? Their scenario makes it seem like if the bad guy kills the one and only student in the shcool with a gun, the killing would go on unimpeded.
If you like the IRS, DMV and the Post Office, you will love Obamacare!

I have to agree with a quote from former Treasury Secretary William E. Simon: "Bad politicians are sent to Washington by good people who don't vote."
