Church needing security?

I've never understood how a church could need security and honestly I have always been unhappy with the church's that had it. I've always felt that the church was the one place on this earth that I was protected. However,yesterdays events prove that evil is everywhere. The victims in yesterday situation could have easily been me or you. Lets remember everyday that God is in control and take out a few moments to ask for his protection and loving arm. To the families involved I send my condolences.
