Beware of the Simplistic Solution
In light of the heinous crime committed at VaTech yesterday, I predict that we will see even more simplistic solutions than we've already heard in the last 24 hours.
Further prediction: these solutions will do nothing positive, but will make you feel better about things. Like many of the reforms proposed to increase flight security, they only restrict what the law-abiding are permitted to do. And let's face it, if you're determined to kill someone, you're not going to feel a lot of remorse about taking a weapon into a weapons-free zone.
One last prediction: anyone peddling simplistic solutions are also looking to sell something.
