Adapt or GTFO
Their first complaint about jurors not doing their own research, I agree with... but that's nothing new. Here in the states - sorry I'm not too familiar with how juries work in the UK - there have always been problems with Jurors watching news stories or reading articles about the trial they are sitting in on, which typically leads to their dismissal or a mistrial. A jury should only be judging based on what is presented in court. Blaming this pre-existing condition on teh interwebz is ill-informed.
The second complaint about victims finding their own perps online thereby invalidating a photo or some other type of "pick them out of a lineup" challenge... on that all I can really say is WOW, are these officers completely batshit retarded? It's possible that the lineup is some sort of procedural requirement I guess, but this still makes no sense. What they're ultimately complaining about is the public doing their job - which is not a new phenomenon either.
Strangely enough my friend's car was stolen the night before last. He went online to check his toll records and saw that it had exited off the tollway in a neighboring city at 3 AM. He informed the investigating officer, who - we suspect - contacted the neighboring city's police department, who put out an APB on his vehicle and it was found within roughly 14 hours of being stolen. I raise this issue for one point only - the officer investigating the issue did not get all pissed off about the victim helping out his investigation. We were able to provide useful information that would have taken him much longer to find - assuming he ever looked where and how we looked to begin with - and it helped him solve the case. In this case everybody wins.
For the sexual assault/rape case referenced in the article I can see how both the victim and her friend repeatedly looking at the perp's Facebook page could make the prosecution more difficult, but telling an assault/rape victim to sit around and do nothing while the cops go off and do their thing is somewhat offensive - as is the coppers whinging about it after the fact like 11 year old girls.
They need to grow up or GTFO
