a) Your reply is non-responsive the the nature of the filter. I won't just take someones word a filter works. I've seen too many that only appear to work.
b) Filters are flawed technical solutions to a social problem. They give a false sense of security when the only real security is looking over their shoulder every few minutes.
c) Cases listed include 12 year olds that defeated filters to view porn. The filters likely bought the kids time. (assuming they kept the screens pointing so they could supervise). Other heinous crimes listed are the responsibility of the scumbags not the library that they happened to occur at.
d) Some parents want only a pre-filtered white list of acceptable content available in librarys. That is a good solution for a dedicated childrens machine but not acceptable for adults doing research.
a) Certainly a library director's words carry more weight than mine, despite your saying, "I won't just take someones word a filter works."
b) Asked and answered by the US Supreme Court. Next?
c) I agree library filters will never be perfect. Does that mean CIPA and US v. ALA can never apply? But again, asked and answered by the US Supreme Court. Next?
d) The bad guys doing the crimes are not using the filtered children's computers. They are using the unfiltered adult ones. CIPA says all computers must be filtered. And one town that filtered only the children's computers had an incident then regretted not installing them on all computers in the first place.
Did you notice it often takes a rape or molestation before legal filters are applied? Do you want your kid to be the test case?
