Are We Moving Toward Overkill?

I have no problem with security when it helps to make me feel secure from potential threats. Security is high in Beijing, and whether you believe there are threats or not, it's only getting higher. The attack today in Xinjiang will only make the government more antsy about things in Beijing. In many major cities around the world, its common to go through airport style metal detectors and have your bags scanned when you enter important office buildings. Thus, it should come as no surprise that metal detectors and security checks will become the norm at major office buildings around Beijing.

So now, a number of friends are complaining that from the time they leave their house to the time they get into the office each morning, they'll face 3 security checks. Is Beijing going a bit too far with the idea of safety?
