From what I understand of public use services, the learning center can't be held responsible for what every Tom, Dick or Harriet uses their PCs for, and I am sure they have disclaimers as to the use already, taking away any liability, however, any possible negative publicity may guide them in the direction of assisting the police. DPA does not apply if a criminal act has been committed to the center would be inclined to provide help if need be.
But again, lets watch how we phrase things here, it could harm any investigation if we speculate further and I think if anything, we want Sue to get a result out of this.
I'm still so narked by this. Really really am.
