Va. Tech Killer Ruled Mentally Ill by Court; Let Go After Hospital Visit

These news facts makes it seem like a number of people knew he had mental problems.
So does any of the blame for what happened fall on the lap of our PC culture?
We can't accuse anyone of anything or say anything that might offend anyone...so maybe that is what happened here...
PC destroys any shred of common sense. Back when we didn't have a liberal PC world, common sense took place.
When someone seemed mentally ill, we told them that and sometimes made them get treatment...now people are afraid to be singled out by the PC thought police, they are afraid that they might offend someone or get sued for hurting someones feelings.
I am certain that this would not have happened if it were not for our liberal PC society...this guy would have been locked up long ago...
