How did the Hartford Police outside investigation actually get started? Well first off, I don't think any of the information was even public until it started getting posted here. Eventually attorneys began calling for outside investigations, it started with the Attorneys for Lt. Neville Brooks after he was abruptly removed from his position as Commander of Internal Affairs. It escalated after Rashim Campbell was exonerated of criminal allegations against him when a jury acquitted him. His attorney has raised allegations of improper techniques and even possibilities of false testimony by the IAD investigator, Lt. Robert Ford.
The attorney's for Lt. Brooks even went so far as to mention "the blog" in their request for an outside investigation. It appears that there was more than enough pressure brought to bear on the Chief and Mayor before they launched their "independent investigation". On Thursday, Chief Roberts, in a memo to his officers and staff, advised that the investigation was ordered after he informed the Mayor of "internal matters". I think it was more outside pressure than any move to fully investigate the matter by the Mayor or Chief that led to the outside investigation.
Here is the Chief's memo to "all personnel". The actual investigation is expected to begin on Thursday.
