File on high-risk offenders found in street

Presumably a majority of the information found would have been a matter of public record, although if you have ever tried to search such public record, information is hard to come by.
What wasn't in the public domain arguably should have been.
The greatest risk from such a discovery is potentially on those who release such offenders back in to the community, not the offender themselves ... after all depending on the crime, they will be well aware of feeling toward their offending from within prison.

Quite simply there should be provision for greater public scrutiny on these matters than is currently the case.
