Interesting point beej, I've also noticed a decline in trust for others, but I think it has more to do with mass media continually emphasising the bad in the world, spreading fear.
The religions do this as well, at the same time they are committing the crimes.
The base of monotheist religions is fear and guilt, this breeds mistrust. As most humans can no longer see the energy of another beyond the surface, there will be no trust. This is the forgotten sense.
When we can only see differences there is no trust.
When we despise the person because of the belief, there is no trust.
