if someone had reported at the time, who knows what may have occured. im commenting on what happens now with investigations of breaches in the past.
Not sure I quite follow. Are you suggesting that if a law was broken say 12 months ago there should be no investigation? All police investigations are into events that took place "in the past". If the police didn't investigate crimes that took place in the past, they wouldn't have very much to do.
Maybe I've just been whooshed so hopefully you could expand on your line of reasoning here.
